Summary for the risk of pre‐eclampsia (not defined) in women with GDM

Probably ineffective or harmful interventions (more evidence needed): indicating that the review found moderate‐quality evidence suggesting lack of effectiveness for an intervention, more evidence needed Moderate‐quality evidence showed no clear difference for the DASH diet versus control diet with matching macronutrient contents or insulin versus oral therapy. No conclusions possible: low‐ to very low‐quality evidence, or insufficient evidence to comment on the effectiveness, more evidence needed Low‐quality evidence showed no clear difference for energy‐ versus no energy‐restricted diet; high‐ versus low‐unsaturated fat diet with matching calories; lifestyle intervention versus usual care or diet alone; exercise versus control; intensive management versus routine care or insulin type A versus B. Very low‐quality evidence showed no clear difference for metformin versus glibenclamide; soy‐ versus no soy‐protein diet or managed by self‐ versus periodic‐glucose monitoring or post‐ versus pre‐prandial glucose monitoring
