📊 Evidence by Outcome
Strong meta-analytic evidence from 28-46 RCTs. Reduces FPG by 0.54-0.86 mmol/L and HbA1c by 0.54-0.73%. Comparable to metformin in some head-to-head trials.
46 studies • Consistency: High • Effect: Moderate
Consistent reductions in TG, TC, and LDL. Most effective as adjunct to statins. 44-RCT meta-analysis supports cardiovascular benefits.
44 studies • Consistency: Moderate • Effect: Moderate
Significant BMI reduction (MD -1.07) in metabolic syndrome populations. AMPK-mediated mechanism. Not a standalone weight-loss agent.
10 studies • Consistency: Moderate • Effect: Small
👥 Community Insights
