Effects of soy protein supplementation on serum
adiponectin concentration
According to our analysis on 14 studies, in overall, soy and soy product
consumption had significant effect on adiponectin concentration: WMD =
0.09; 95% CI: 0.04, 0.15; P = 0.001. There was significant heterogeneity
among the studies (Cochran’s Q test = 165.27, P = 0.000,
I2 = 92.7 %). Subgroup analysis of gender of
participant, baseline BMI, dose of soy protein, duration of studies,
supplementation type and study design had no significant effect on
adiponectin concentration in any subgroups. The results of subgroup
analysis are shown in Table 3 and the forest plot is shown inFigure 2 .
