 ESC 2024 mediation analysis quantifies specific mediator contributions: hsCRP (inflammation) accounts for 42.1% of CV benefit, body weight only 19.5%, waist circumference 64.0%. Joint mediation of ALL measured factors (weight, inflammation, HbA1c, waist) explains only 31.4% (95% CI: -30.1% to 143.6%), leaving ~68.6% unexplained. This confirms the weight-independence finding from the Lancet 2025 prespecified analysis and adds the specific breakdown showing inflammation mediates MORE than weight loss.

+SELECT trial prespecified analysis (N=17,604, published Lancet November 2025) confirms semaglutide reduced MACE consistently across ALL baseline BMI and waist circumference categories with no evidence of treatment heterogeneity by adiposity level. Approximately 67% of MACE benefit is independent of adiposity/weight change. This is stronger evidence than the ESC 2024 abstract because it's a prespecified, not exploratory, analysis. The flat treatment effect across weight-change categories directly contradicts the hypothesis that benefit concentrates in patients achieving significant weight loss.

+Complementary ESC 2024 mediation analysis (Colhoun/Lincoff) quantifies specific mediators: body weight mediates only 19.5% of CV benefit, while hsCRP (inflammation) mediates 42.1% — making anti-inflammatory pathways the largest single measured mediator, more than double the contribution of weight loss. Joint mediation of all measured factors accounts for only 31.4% (95% CI: -30.1% to 143.6%), leaving ~68.6% pleiotropic/unexplained. The convergence of two independent analyses (67% and 68.6% weight-independent) strengthens the claim that GLP-1s function primarily as anti-inflammatory cardiovascular drugs.

 PRIMARY CONNECTION: [[GLP-1 receptor agonists are the largest therapeutic category launch in pharmaceutical history but their chronic use model makes the net cost impact inflationary through 2035]]
 WHY ARCHIVED: Closes active thread on GLP-1 CV mechanism; establishes weight-independence as the primary clinical finding; connects GLP-1 benefit to SDOH-generated inflammatory pathways
 EXTRACTION HINT: Focus on the 67-69% weight-independence figure and the hsCRP mediation (42.1%) — together these establish the anti-inflammatory mechanism. Extract as mechanism claim, not just efficacy claim. Consider whether this should be a divergence with the existing GLP-1 claim that frames the drug primarily through metabolic/weight-loss lens.
