GDM and children asthma
Four studies were included in the subgroup analysis. The study population of one of study was divided into four groups based on preterm or term delivery (Very preterm <32 weeks; Moderate preterm 32+0–33+6 weeks; Late preterm 34+0–36+6 weeks; Term ≥37 weeks)(7). The pooled effect estimate between GDM and children asthma was 1.13 (95% CI: 1.01, 1.27). Due to the heterogeneity of the study (I2 = 58.3%, P = 0.026), a random effect model was used to show the relationship between GDM and children asthma .(Figure 3(a) )
