Significant: p-value 0.05; Marginally Significant (0.05 ≤ p-value 0.1). SDM: standardized difference in means; DM: Difference in means; CI: confidence intervals; n: total number of studies; NT: total number of participants; I2: Heterogeneity Index; WC: Waist Circumference; T-C: Total Cholesterol; HDL-C: High Density Lipoprotein Cholesterol; SBP: Systolic Blood Pressure; DBP: Diastolic Blood Pressure; FMD: Flow Mediated Dilation. 1 GRADE quality of evidence downgraded from high to moderate or low in the presence of serious risk of bias across studies and (or) serious risk of reporting bias; 2 serious risk of bias across studies: more than 50% of the studies had unclear allocation concealment, no double-blind studies and unclear reporting of dropouts; 3 serious risk of reporting bias: Eggert p-value 0.05 and more than 50% of small studies with limited number of participants.
