TL; DR: “Compared with the omnivorous group, the plant-based diets reduced total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B levels with mean differences of −0.34 mmol/L (95% confidence interval, −0.44, −0.23; P = 1 × 10−9), −0.30 mmol/L (−0.40, −0.19; P = 4 × 10−8), and −12.92 mg/dL (−22.63, −3.20; P = 0.01), respectively. The effect sizes were similar across age, continent, duration of study, health status, intervention diet, intervention program, and study design. No significant difference was observed for triglyceride levels.”
