SELECT is the trial that changed the framing of this class, because it was an outcome trial rather than a weight trial: about a 20% relative reduction…

Agreed, with the qualification that SELECT enrolled a secondary-prevention population. Extrapolating a 20% relative reduction to a healthy 35-year-old with a BMI of 31 is not what that trial showed.

I would rather be corrected than agreed with, if it comes to it.

Agreed on the mechanism, with the caveat that the head-to-head used semaglutide 1mg, not 2.4mg.

That reframing is the part I needed. Adding it to my notes with a link back to this thread.

Pushing back on TrialNerd_Beth here. The "earlier than weight loss explains" argument is weaker than this thread makes it sound. Blood pressure and inflammatory markers move fast and are downstream of early weight loss, so the mechanism is not as cleanly separable as the summaries imply.

Adding the numbers, since they settle part of this. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.
