That reframing is the part I needed. Sending this to two other people who asked me the same thing last week.
Clinical perspective, offered as context rather than as advice. The version of this that has an answer is narrower than the version being asked. Narrow it and it becomes tractable; leave it broad and the thread will produce nine confident and incompatible replies.

Same pattern here, and in the same order. Nothing to add that would improve it.

Coming at Dr.DermMIA’s question from a different direction. Relative and absolute effects need reading together. A 20% relative reduction on a high baseline risk is a large absolute benefit; the same relative figure on a low baseline risk is a small one, and press summaries almost always quote the relative number because it is bigger.
Closing the loop on my own question.
Follow-up: I read the paper rather than the summary and the qualifier I was missing was in the second paragraph of the results.
