My reason for being on this is cardiovascular rather than cosmetic, which puts me in a small minority in most of these threads.

Relative versus absolute is the distinction that gets lost: a 20% relative reduction on a high baseline risk is a large absolute benefit, and the same relative figure on a low baseline risk is a small one.

The bit I cannot resolve on my own is how much of the SELECT benefit is plausibly independent of the weight loss, and whether that distinction changes anything practical.

I would rather have one careful answer than five confident ones.

Taking the question as asked, rather than the general version of it. The glucagon component looks paradoxical and is not. Glucagon receptor agonism raises energy expenditure and drives hepatic fatty-acid oxidation, and its hyperglycaemic tendency is offset by the GLP-1 arm's insulin secretagogue effect. Net result: intake down from GLP-1/GIP, expenditure up from glucagon, glycaemia neutral or improved. It is a balancing act, and it is why the liver-fat results are the most interesting part of the dataset.

Fair, but phase 2 tolerability figures rarely survive contact with phase 3 scale. Triple agonism means three receptor systems generating adverse events, and the dropout column is the one I would read first when the larger trials report.

Second this. Nothing to add that would improve it.

Adding the clinical framing, because it changes how the question reads.

Lp(a) and cardiovascular risk: a nuance that matters. Unlike most lipid markers, Lp(a) is 90%+ genetically determined and doesn't really change with weight loss or GLP-1 therapy.

My Lp(a) has remained at 84 nmol/L across all time points. If yours is elevated (>50 nmol/L), you need additional risk mitigation strategies regardless of your GLP-1 response. Don't assume your medication is covering all cardiovascular risk factors.
