## In plain language

A randomized trial that asked whether treating women who have gestational diabetes lowers the chance of serious problems for their babies. Women were given diet advice, blood sugar monitoring and insulin if needed, or routine care. Serious complications were less common in the treatment group.

## Technical summary

Randomized clinical trial (2005, the trial titled Effect of treatment of gestational diabetes mellitus on pregnancy outcomes). Women between 24 and 34 weeks of gestation with gestational diabetes were assigned to the intervention (dietary advice, blood glucose monitoring and insulin therapy as needed) or routine care; the abstract counts 490 women in the intervention group and 510 in the routine-care group. Results are recorded as separate claims on this page. No registry number appears in the abstract. Only the abstract was read.
