About the application:

Occasionally in medicine, we really need to "do the math". This apk will assist. EBM Statistics Calc let's a clinician do calculations that are hard or impossible to do in one's head. A clinician can receive NNT's (number required to treat) from rates, percentages, or raw happening and patient numbers. And a clinician can use sensitivity and specificity or likelihood ratios (LR+, LR-) to go from a pretest probability to posttest probability and positive predictive value and negative predictive value. Although these calculators themselves are somewhat novel for apks, the special program in this apk is for educators. Students and residents have a hard time understanding how the utility of a try can vary with pretest probability. Instead of saying it in words and hoping they receive it, now you can demonstrate it. A try might perform well, giving awesome PPV and NPV, when pretest probability is in a certain range. But slide that pretest probability up or down and see the diagnostic utility change with the numbers flying right before your eyes. The program also shows a student that in a lot of cases, an imprecise estimate of pretest probability doesn't much matter. Various doctors might judge a clinical case to recommend likelihood of illness (pretest probability) of 40%, 50%, or 60%. The slider program shows that the differences may not matter, and the try in mind will render awesome clarity regardless of differing opinions on pretest probability. The apk is written for clinicians, students, residents, and especially educators, in any discipline of medicine. As a clinician and educator myself, I would be grateful for feedback to create the program better.
