This number represents the reciprocal of the absolute risk reduction and gives the reader an understanding of how many patients a clinician would have to treat to see the desired outcome. As researchers learn more about disease processes, clinical trial design is also changing and becoming more complex. This flow diagram is usually the first figure in the paper, and it shows the flow of subjects from recruitment through the end of the study (or early exit from the study). In contrast, statistical tests for time-to-event data compare the survival rate, which is essentially an estimate of the slope across the entire follow-up period. How to Read a Clinical Trial Paper I once participated in a clinical trial to develop a malaria vaccine. If a study is initially designed to test for superiority but this outcome is not found, switching to an equivalence study would be inappropriate for 2 reasons: (1) the acceptable difference would not have been defined in advance, and (2) the sample size would be too small.

Start instantly and learn at your own schedule. PMC legacy view Typically, the design of an equivalence study requires that the 95% confidence interval of the difference between the treatments be less than the previously defined acceptable difference. Another consideration with graphs is that, while plots of means without an indication of variability may be more aesthetically pleasing, these figures do not give the reader an understanding of the variation in the data.
