Meta-analysis showed a trend toward reducing the level of LDL (MD = -2.34; 95% CI:-5.67 to 0.99; I 2 = 13%; p = 0.17) by fixed effects model (Fig. 2 c) and increasing the level of HDL (MD = 2.33; 95% CI: -0.27 ~ 4.92; I 2 = 82%; p = 0.08) (Fig. 2 d), but the beneficial effects of Mediterranean diet compared with control diets were not statistically significant.
