I think I remember UW having a few examples of these questions.
There are only a few on the test, so there's no need to stress too much. The questions themselves aren't particularly crazy. They tend to ask stats and epidemiology questions in this context now, but it's mostly just critical reading of a non-clinical vignette. You have to understand the definitions and how terms like sensitivity, specificity, PPV, NPV, etc are all used in abstracts/drug ads. If you can get the typical USMLE stat questions correct consistently, I don't really think the new format ads a significant degree of difficulty.
