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

So the question, as narrowly as I can put it: 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.

I want to bring up the cardiovascular angle on cardiovascular risk.

The SELECT trial demonstrated a 20% reduction in MACE with semaglutide 2.4mg[1]. This is practice-changing because the CV benefit appears to be independent of the degree of weight loss — suggesting direct vascular and anti-inflammatory mechanisms.

For cardiovascular risk, this means we need to think beyond the primary outcome and consider the cardiovascular implications. The all-cause mortality reduction (HR 0.81) is the most clinically meaningful signal.

NNT calculation for cardiovascular risk clinical endpoints: NNT = 1/ARR (absolute risk reduction).

From SELECT trial: MACE at 39 months — 6.5% semaglutide vs 8.0% placebo. ARR = 1.5%. NNT = 67 over 3.3 years.

Compare to established therapies:

InterventionNNTTimeframe
Semaglutide (MACE)673.3 years
Statins primary prevention (MI)~1005 years
Aspirin secondary prevention~772 years

These NNTs are clinically meaningful and comparable to accepted cardiovascular interventions.

Can confirm. Same sequence, different timescale.

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

Dizziness and cardiovascular risk: I was lightheaded for the first 3 weeks. Root cause was a combination of reduced caloric intake and mild dehydration.

Fix: minimum 80-100oz water daily, don't skip meals even if you're not hungry (eat small protein-rich snacks), and stand up slowly from sitting/lying positions. Also check your blood pressure — GLP-1-induced weight loss can make BP meds too strong, requiring dose reduction.
