Summary for the risk of development of type 2 diabetes for women 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 therapy (up to one year postpartum). Low‐quality evidence showed no clear difference for lifestyle intervention versus usual care or diet alone (diagnostic test or timeframe not defined). Very low‐quality evidence showed no clear difference for high‐ versus low‐unsaturated fat diet with matching calories using the Oral Glucose Tolerance Test (OGTT) for diagnosis of type 2 diabetes at one‐ to two‐weeks postpartum or at four to 13 months postpartum. There was no clear difference for the treatment with low‐GI diet versus high fibre moderate‐GI diet using the OGTT at three months postpartum. There was no clear difference between insulin and diet up to 15 years follow‐up
