None of the studies reported on the mode of diagnosis or the size of the defect. The pooled proportion of IH with all anomalies combined was 0.03 (95%-CI, 0.02 – 0.05; I2 = 79%, p ≤ 0.01). Separate pooled proportions were calculated for the following birth defects: Gastroschisis 0.10 (95% CI: 0.06-0.17; n = 142/1273; I2 = 86%; p ≤ 0.01); Anorectal malformations 0.01 (95% CI: 0.00-0.05; n = 4/426; I2 = 29%; p =
