Summary for the risk of death or serious morbidity composite for infants born to mothers with GDM

No conclusions possible: low‐ to very low‐quality evidence, or insufficient evidence to comment on the effectiveness, more evidence needed Moderate‐quality evidence showed no clear difference for insulin versus oral anti‐diabetic pharmacological therapies. Moderate‐quality evidence showed no clear difference exercise versus control although the direction of the effect suggested benefit favouring exercise. Low‐quality evidence suggested a reduction in the risk of death or serious morbidity composite outcomes for babies born to mothers with GDM who were treated with metformin compared to glibenclamide. Very low‐quality evidence showed an increased risk of a death or serious morbidity composite for twice daily insulin regimen versus four times daily insulin regimen. Very low‐quality evidence showed no clear difference for ethnic specific diet versus standard healthy diet; lifestyle intervention versus usual care or diet alone; or managed by telemedicine versus standard care for glucose monitoring
