I know nothing about this field, and the actual paper is behind a paywall, but it says that after the "exposure to AI", the adenoma detection rate (ADR) dropped from 28.4% to 22.4%. As a layman, does ADR simply mean suspicion, or does it mean they correctly and accurately saw adenomas in 28.4% of patients before and now the rate is only 22.4%. Or just that they suspected it 6% more before? Does the actual paper detail if they simply stopped seeing illusions, or did they actually stop seeing meaningful things they used to see? I'm sure the paper goes into more detail, but I'm more interested in the false positive vs false negatives than just overall %.
