Altman DG (1991) Practical statistics for medical research.The 95% confidence interval is calculated according to Sheskin, 2011. The two-sided P-value is based on the cumulative binomial distribution. When the (two-sided) P-value is less than the conventional 0.05, the conclusion is that there is a significant difference between the two proportions.

The program gives the difference between the proportions (expressed as a percentage) with 95% confidence interval. in studies in which patients serve as their own control, or in studies with "before and after" design. In the case of a 3 x 3 (3 columns and 3 rows) there are. ROC curves are compared based on calculating the difference between the areas under the curves using standard error, 95% confidence interval and P-value.The McNemar test is a test on a 2x2 classification table when the two classification factors are dependent, or when you want to test the difference between paired proportions, e.g. The Bonferroni correction for a chi-square analysis is the number of comparisons being completed (i.e., row x columns comparisons/tests). You can choose threshold values in the dot diagram and the corresponding specificity and sensitivity is automatically calculated. The area under the curve is calculated with a 95% confidence interval and standard error.
