I seriously love this app. Why don't more people use this? It's exactly what I need (without any clutter) to calculate my patient's risk of having a disease. If you don't understand the statistics, I'll tell you: to calculate a patient's risk of having one of the things you've got on your differential, you need their pretest probability of having that specific disease and the likelihood ratios of the tests you're doing/considering doing. And that's what is in this app. Awesome.
Just what the doctor ordered (groooan, bad pun). This app does what it should and tracks down a lot of the numbers for you. Nicely done. Including a normogram in a future release wouldn't hurt
