GDM, gestational diabetes mellitus; GTT, glucose tolerance test; PP, postpartum.

Impaired fasting glucose defined as fasting glucose 100–125 mg/dL;

Impaired glucose tolerance defined as 2-hour glucose 140–199 mg/dL;

Overt type 2 diabetes mellitus defined as fasting glucose >125 mg/dL or 2 hour glucose >199 mg/dL;

Among those who were not already diagnosed with dysglycemia clinically.
