1. The slider tool shows that the differences may not matter, and the test in mind will render good clarity regardless of differing opinions on pretest probability.
2. 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.
3. The tool also shows a student that in many cases, an imprecise estimate of pretest probability doesn't much matter.
4. Students and residents have a hard time understanding how the utility of a test can vary with pretest probability.
5. A test might perform well, giving good PPV and NPV, when pretest probability is in a certain range.
6. But slide that pretest probability up or down and see the diagnostic utility change with the numbers flying right before your eyes.
7. A clinician can get NNT's (number needed to treat) from rates, percentages, or raw event and patient numbers.
8. Different doctors might judge a clinical case to suggest likelihood of disease (pretest probability) of 40%, 50%, or 60%.
9. The app is written for clinicians, students, residents, and especially educators, in any discipline of medicine.
10. As a clinician and educator myself, I would be grateful for feedback to make the tool better.
11. Although these calculators themselves are somewhat novel for apps, the unique tool in this app is for educators.
