The majority of outcome data related to GDM (n = 45 studies), followed by hypertensive disorders (n = 20; including preeclampsia and pregnancy‐induced hypertension), measures of insulin and glucose (in the absence of reporting GDM diagnosis, n = 7), maternal lipids (n = 6), caesarean delivery (n = 5), composite outcomes (n = 4), induction or assisted deliveries (n = 3), metabolic syndrome (n = 2), non‐spontaneous labor (n = 1), and gestational weight gain (n = 1) (Table S4). The gene discussed is INS; the disease is metabolic syndrome.
