Adjusted for maternal age (years), race/ethnicity, physical activity (MET-minutes/week), prepregnancy BMI (kg/m2), and randomization condition.
a
Overall Optimal Glycemic Control: ≥80% of all fasting (<95 mg/dL) and 1-hour postprandial glucose measurements (<140 mg/dL) within designated range.
b
REF: reference category.
CI, confidence interval; OR, odds ratio.
c
Defined as ≥80% of all capillary glucose measurements for a given time point within the defined targets.
