Figure F1 is a bar graph that shows the distribution of sample sizes of studies of diagnostic values of tests for UI. The data came from the analysis of the sample sizes of 99 studies that reported diagnostic values of the tests for UI. The horizontal axis represents the following categories of the sample size of the studies: more than 10,000, more than 1,000, between 500 and 1,000, between 100 and 500, and less than 100 enrolled subjects. The vertical axis represents a number of studies. Black bars demonstrate the number of the studies for each category of the sample size. The figure demonstrated that the majority of the studies (56 studies) enrolled between 100 and 500 subjects.
