<p>The example that you mention is interesting, but it might be better to frame the question in a way such that it doesn't become a question about ethics of medicine and deals instead with the different aspects (among which one is the statistical aspect) separately.</p>
<p>A discussion about ethics is not on-topic here. For the specific example that you mention the discussion about ethics would also only muddle the technical approaches that are relevant in the discussion. The technical approaches are ontopic, but the discussion is not.</p>
<p>In principle questions that involve ethics are not off-topic, anything that is about statistics is on-topic, but the questions should not become broad, unclear, opinion, etc. It are those aspects that make questions about ethics in practice off-topic, but it is not the ethics that is in principle off-topic.</p>
