What do we already know about this topic?

• Glycemic control varies among different cohorts of pregnant women with diabetes.
• Most studies examining differences between groups using continuous glucose monitoring (CGM) data were performed with older CGM systems worn for 2-7 days.

How was this study conducted?

• This study examined differences in glycemic control and glycemic variability (GV) between pregnant women (n=32) with T1D (n=20), T2D (n=3), or gestational diabetes (GDM; n=9) in the 2nd and 3rd trimesters using the Dexcom G6 CGM system, worn for 10 days as part of a pregnancy CGM accuracy trial.
• Pair-wise comparisons were made between groups and group heterogeneity testing was performed.
• No adjustments were made for multiple comparisons analyses.
