Figure 2. Risk of gestational diabetes among women born preterm, with low birth weight, or small-for-gestational-age status
Effect size (ES, represented as adjusted odds ratios); CI, confidence interval. ES was determined using the random-effects model weighted by the inverse of the variance estimate. Squares represent ES, with marker size reflecting the statistical weight of the study, obtained using random-effects meta-analysis; horizontal lines represent 95% CIs; diamonds represent the subgroup and overall odds ratios and 95% CIs for gestational diabetes.
