FIGURE 2.
Beta regression coefficients describing the association between prepregnancy body mass index (BMI) and offspring's insulin level without (upper panel; heterogeneity: I 2 = 71.81%, p = 0.014) or with adjustment for offspring's BMI (lower panel; I 2 = 40.32%, p = 0.187). Black squares show beta values with the area reflecting the weight assigned to the individual studies. Horizontal bars indicate 95% confidence intervals. Diamonds show the overall point estimate with 95% confidence intervals
