FIGURE 4.
Beta regression coefficients describing the association between gestational weight gain and offspring's insulin level without (upper panel; heterogeneity: I 2 = 0%, p = 0.992) or with adjustment for offspring's body mass index (lower panel; I 2 = 22.85%, p = 0.274). 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
