DirectionalProcedure Efficacy Interpretation
While the colonoscopy's 95% success rate at spotting large growths is reassuring, the sobering 22% polyp miss rate reminds us this is a high-stakes game of hide-and-seek where the quality of the hunt, from preparation to withdrawal time, directly dictates whether we achieve that celebrated 80% reduction in cancer deaths.
