Screening Tests – Cumulative Incidence of False Positives

It’s easy to think of medical tests as black and white. If the test is positive, you have the disease; if it’s negative, you don’t. Even good clinicians sometimes fall into that trap. Based on the pre-test probability of the disease, a positive test result only increases the probability by a variable amount. An example: if the probability that a patient has...

On the nature of “alternative” medicine cancer cure testimonials

No doubt you’ve come across them before, either on the Internet, printed advertisements, or radio and TV ads: Alternative medicine cancer “testimonials.” They are the primary means by which “alternative” therapies for cancer (or just about any other disease) are promoted and the primary “evidence” that is used to “prove” the efficacy of non-evidence-based therapies. There’s no doubt that they sure can...
