Read past ‘risk halved’ | Medical student recall

A 35-second silent, caption-led lesson for medical students. No narration or music. Pause at the question and then check your reasoning. 0:00 Another fictional headline — Group A: 1 in 100. Group B: 1 in 200. Same follow-up period. No real study is described. 0:07 Use one denominator — That is 10 versus 5 per 1,000. The relative reduction is 50%. 0:14 Your turn · pause — What is the absolute difference in risk, in percentage points? 0:21 0.5 percentage points — 1% minus 0.5% = 0.5 points. A relative percentage needs its starting risk. 0:28 Ask what is missing — Who was studied? What outcome? How long? What uncertainty and design? The arithmetic alone proves no treatment benefit.
