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.
