Semaglutide and Cardiovascular Outcomes in Patients with Type 2 Diabetes (SUSTAIN-6).
N Engl J Med (2016) · Rct · n=3297
Pre-approval cardiovascular-safety RCT in 3,297 patients with type 2 diabetes at high cardiovascular risk, semaglutide (0.5/1.0 mg/week) vs placebo for 104 weeks
Meta-analysis (Brown 1999) found a roughly linear -0.045 mmol/L total-cholesterol drop per gram of soluble fiber within a 2-10 g/d range; the effect is small and plateaus, and GI tolerance limits higher intakes. Effect is weaker in people with normal baseline cholesterol.
