Evidence ladder
How far up the ladder this claim has climbed. A high consensus on a low rung means "consistent so far," not "proven in people."
Top evidence so far: Human trials (RCT / n-of-1)
How the studies fall
What the evidence shows
Ezetimibe is cancer-NEUTRAL in randomized data (IMPROVE-IT, n=17,708 - no malignancy excess, rebutting an earlier SEAS signal). A tiny observational arm hints at lower cancer with statin+ezetimibe but is confounded. Honest verdict: cancer-neutral; 'prevents cancer' not supported, 'causes cancer' refuted.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
