Figure 51 is a metagraph comparing rates of preeclampsia between women treated for GDM and those who were not. Three RCTs contributed data from 2,014 participants. Pooled results favored treatment (RR 0.62, 95% CI, 0.43, 0.89; I²=16%). In addition, one cohort study contributed data from 258 patients, demonstrating no significant difference between groups (RR 0.97, 95% CI, 0.43, 2.15).
