  • Peer-to-peer review: what actually happens on the call Replied, post #3 · Access › Insurance & coverage · 27 Jul 2026 · 1 like I disagree with the reply above, and I think the disagreement is substantive rather than terminological. The distinction being drawn does not survive when you look at…

  • Revisiting: PCOS and metabolic overlap: what is and is not studied Replied, post #45 · Clinical › Comorbidities · 24 Jun 2026 · 6 likes Having read the exchange above, I think I was wrong earlier in this topic and I want to say so plainly rather than quietly editing.
