occurrence of one or more events that might indicate possible problems in study
design (ambiguous inclusion criteria, misinterpretation of questionnaire items)
or product safety (occurrence of serious adverse events, abnormal lab tests, or
other safety markers). Enter the prevalence rate you want to be able to detect
(like one in a hundred), and the probabibility you want to have of seeing at
least one such event in your sample (like 95% probability), and the page will
tell you how many subjects you need in the study. (added 08/05/2015)
