Assessment of the optimal cutoff value of fasting plasma glucose to establish diagnosis of gestational diabetes mellitus in Chinese women

Our aim is to assess the optimal cutoff value of fasting plasma glucose (FPG) in Chinese women at 24–28 weeks’ gestation by performing oral glucose tolerance test (OGTT) to improve diagnostic rate of gestational diabetes mellitus (GDM).
