Biliary sand may eral arthritis affects joints on both the left and right be looked upon as a stage of growth between bilary sides of the body. The composition of biliary sand bile A yellow-green fluid that is made by the liver varies but is similar to that of gallstones, the most and stored in the gallbladder. Bile passes through common components being cholesterol crystals and the common bile duct into the duodenum, where it calcium salts. The principal components of bile or it may cause intermittent symptoms, including are cholesterol, bile salts, and the pigment biliru- pain in the abdomen, nausea, and vomiting, partic- bin. An increased plications, including inflammation of the pancreas amount of cholesterol in the bile overwhelms the (pancreatitis) and inflammation of the gallbladder dissolving capacity of the bile salts and leads to the (cholecystitis).

Bile acid most common particulate components are choles- resin may be prescribed, together with a statin med- terol crystals and calcium salts. Biliary sludge has ication, for patients with heart disease, to reduce been associated with certain conditions, including cholesterol. Cholestyramine (brand name: rapid weight loss, fasting, pregnancy, the use of cer- Questran) and colestipol (Colestid) are examples of tain medications (for example, ceftriaxone, bile acid resins. Side effects may include constipa- octreotide), and bone marrow or solid organ trans- tion, bloating, nausea, and gas. However, it most commonly occurs in resin is not absorbed, it may interfere with the individuals with no identifiable conditions. Biliary absorption of other medicines if taken at the same sludge can be considered microscopic gallstones. Biliary sludge usually causes no symptoms, and it may appear and disappear over time. Three main species of these worms— cause more serious complications, including Schistosoma haematobium, S.

A quick informal check of normality is to examine whether the mean and the median values are close to one another buy generic lexapro 10 mg on-line. From the Descriptives table discount 5 mg lexapro with amex, the differences between the median and the mean can be summarized as shown in Table 2. The percent difference is calcu- lated as the difference between the mean and the median as a percentage of the mean. That is, most data values should lie in the area that is approximately two standard deviations above and below the mean. A good approximate check for normality is to double the standard deviation of the variable and then subtract and also add this amount to the mean value. The estimated range should be slightly within the actual range of data values, that is the minimum and maximum values. For birth weight and gestational age, the estimated 95% range is within or close to the minimum and maximum values from the Descriptives table. However, for length of stay, the estimated 95% range is not a good approximation of the actual range. The estimated lower value is invalid because it is negative and the estimated upper value is significantly below the maximum value. If the two estimated values are lower than the actual minimum and maximum values, as in this case, the distribution is usually skewed to the right, indicating positive skewness. If the two estimated values are much higher than the actual minimum and maximum values, the distribution is usually skewed to the left indicating negative skewness. A perfectly standard normal distribution has skewness and kurtosis values equal to zero. Skewness values that are positive indicate a tail to the right and skewness values that are negative indicate a tail to the left. Values between −1and+1 indicate an approximate bell-shaped curve and values from −1to−3orfrom+1to+3 indicate that the distribution is tending away from abellshapewith>1 indicating moderate skewness and >2 indicating severe skewness. Any values above +3orbelow−3 are a good indication that the variable is not normally distributed. The Descriptives table shows that the skewness values for birth weight and gestational age are between −1and+1 suggesting that the distributions of these variables are within the limits of a normal distribution. As for skewness, a kurtosis value between −1and+1 indicates normality and a value between −1and−3 or between +1 and +3 indicates a tendency away from normality. For birth weight and gestational age, the kurtosis values are small and are not a cause for concern. In practice, dividing a value by its standard error produces 32 Chapter 2 Table 2.

However, the valuesin the Extreme Values table are the minimum and maximum values in the data set and these may not be influential outliers. A uni- variate outlier is a data point that is very different to the rest of the data for one variable. An outlier is measured by its distance from the remainder of the data in units of the stan- dard deviation, which is a standardized measure of the spread of the data. A multivariate outlier is a case that is an extreme value on a combination of variables. For example, a boy aged 8 years with a height of 155 cm and a weight of 45 kg is very unusual and would be a multivariate outlier. It is important to identify values that are univariate and/or multivariate outliers because they can have a substantial influence on the distribution and mean of the variable and can influence the results of analyses and thus the interpretation of the findings. For a continuously distributed variable with a normal distribution, about 99% of scores are expected to lie within three standard deviations above and below the mean value. Sometimes a case, that is, a univariate outlier for one variable will also be a univariate outlier for another variable. Multivariate outliers can be detected by inspecting the residuals around a model or by using statistics called leverage values or Cook’s distances, which are discussed in Chapter 5, or Mahalanobis distances, which are discussed in Chapter 7. Outliers may be errors in data recording, incorrect data entry values that can be corrected, or genuine values. When outliers are from participants from another population with different characteristics to the intended sample, they are called contaminants. This happens, for example, when a participant with a well-defined illness is inadvertently included as a healthy participant. Occa- sionally, outliers can be excluded from the data analyses if they are contaminants or biologically implausible values.

Computing per cent changes provides control over the units that the changes are expressed in and their direction of effect order lexapro 10 mg with amex. Paired and one-sample t-tests 103 For the research question buy generic lexapro 5mg on line, the command sequence shown in Box 4. The means in this table show that the per cent increase in weight over 2 months is larger than the per cent increase in length and head circum- ference. The highly significant P values are reflected in the 95% confidence intervals, none of which contain the zero value. The outcomes are now all in the same units, that is per cent change, and therefore growth rates between the three variables can be directly compared. This was not possible before when the variables were in their origi- nal units of measurement. As before, Cohen’s d can be calculated as the mean divided by the standard deviation using the values reported in the One-Sample Statistics table. These differ slightly from the effect sizes computed for a paired t-test because the variables are now in different standardized units and the mean difference and per cent increase have different standard deviations. The effect sizes rank length as having the largest effect size, whereas weight has the largest per cent increase. In some disciplines such as psychology, the t value is also reported with its degrees of freedom, for example as t (276) = 51. However, since the only interpreta- tion of the t value and its degrees of freedom is the P value, it is often excluded from summary tables. Research question The research question can now be extended to ask if certain groups, such as males and females, have different patterns or rates of growth. Questions: Over a 2-month period: Do males increase in weight significantly more than females? Null Over a 2-month period: hypothesis: There is no difference between males and females in weight growth. Variables: Outcome variables = per cent increase in length, weight and head circumference (continuous) Explanatory variable = gender (categorical, binary) Paired and one-sample t-tests 105 The research question then becomes a two-sample t-test again because there is a con- tinuously distributed variable (per cent change) and a binary group variable with two levels that are independent (male, female). Once again, the distributions of per cent change should be fully checked for normality using Analyze → Descriptive Statistics → Explore as discussed in Chapter 2 and that test assumptions have been satisfied before conducting a two-sample or independent t-test. These statistics are useful for summarizing the magnitude of the differences in each gender. In the Independent Samples Test table, the Levene’s test of equality of variances shows that the variances are not significantly different between genders for weight (P = 0. However, the variance in per cent change for length is signif- icantly different between the genders (P = 0. An indication that the variances are unequal could be seen in the previ- ous Group Statistics table, which shows that the standard deviation for per cent change in length is 3. An estimate of the variances can be obtained by squaring the standard deviations to give 10. Thus, the Independent Samples Test table shows that per cent increase in weight is significantly different between the genders at P = 0. This is reflected in the 95% confidence intervals, which do not cross zero for weight, cross zero marginally for length and encompass zero for head circumference. One-sample t-tests can be used to test whether the mean per cent increase is significantly different from zero for each gender. After the commands have been completed, the message Split File On will appear in the bottom right hand side of the Data Editor screen. The One-Sample Test table provides a P value for the significance of the per cent change from baseline for each gender and also gives the 95% confidence intervals around the mean changes. Another alternative to obtaining summary means for each gender is to use the commands shown in Box 4. Although a one-tailed P value is used for the significance of increases in body size because we only expect babies to increase in body size, a two-tailed P value is used for between-gender comparisons because the direction of effect between genders is not certain. Bar charts should always begin at zero so that their lengths can be meaningfully compared. When the distance from zero has no meaning, mean values are best plotted as dot points. For example, mean length would not be plotted using a bar chart because no baby has a zero length. However, bar charts are ideal for plotting per cent changes where a zero value is plausible. The means for males are entered in column 1 and the 95% confidence interval width in column 2.
