Fig. 1 Extent and results of screening for gestational diabetes mellitus at four primary-care sites and overall. Top (stippled) bar of each pair represents percentage of women screened; bottom (open) bar of each pair represents percentage of women whose screened plasma glucose value was more than 139 mg/dl. Number after each bar is actual number of cases.

Fig. 2 Diagnosis of gestational diabetes mellitus at four primary-care sites and overall. Top (stippled) bar of each pair represents percentage of women with positive screening results who were administered an oral glucose tolerance test; bottom (open) bar represents percentage of women with positive results of that test. Number after each bar is actual number of cases.

Fig. 4 Neonatal and maternal outcome of study patients at four primary-care sites and overall. Open portion of each bar represents number of large for gestational age (LGA) infants, and stippled portion represents number of infants with macrosomia (MAC; weight more than 4,000 g). Percentage of cesarean (C) section necessitated by size of infant is depicted by small square in each column; scale is on right vertical axis.
