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. + +### Additional Evidence (extend) +*Source: [[2026-03-30-lancet-select-adiposity-independent-cv-outcomes-2025]] | Added: 2026-03-30* + +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.
