Notation: conditional probabilities: p(a) represents the probability of a p(a | b) the probability of a given that b is true (or has happened).

Upstf: us preventive services task force: screening/testing can be harmful. Upstf weighs the available evidence and comes up with recommendations for testing based on the risks and benefits. Then they grade those recommendations based on how strongly the beliefs are supported by evidence.
