	AUC	95% CI	Cut‐off	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
1‐h PG	0.66	0.58–0.74	175	66.1	58.4	37.9	81.8
2‐h PG	0.72	0.64–0.80	156	74.6	61.7	42.7	86.4
Insulinogenic Index	0.62	0.54–0.70	0.66	65.5	52.6	34.5	80.0
ISSI‐2	0.65	0.57–0.73	0.88	70.7	56.6	38.3	83.5

1‐h PG, plasma glucose at 1 h in the antepartum oral glucose‐tolerance test; 2‐h PG, plasma glucose at 2 h in the antepartum oral glucose‐tolerance test; AUC, area under the receiver operating characteristics curve; CI, confidence interval; IGI, Insulinogenic Index; ISSI‐2, Insulin Secretion‐Sensitivity Index‐2; NPV, negative predictive value; PPV, positive predictive value.
