Associated Factors with Biochemical Hypoglycemia during an Oral Glucose Tolerance Test in a Chinese Population

Table 2

Characteristics of insulin secretion and insulin resistance of biochemical hypoglycemia compared with NGT.

	Glu120 ≤ 3.0 mmol/l	Glu120 > 3.0 mmol/l
n	141	26,465	—
Fasting insulin (μU/ml)	7.4 (5.0–8.9)	8.1 (5.0–9.5)	0.18
Ins30 (μU/ml)	53.0 (27.6–64.9)	47.9 (22.8–60.1)	0.12
Ins120 (μU/ml)	16.3 (7.5–17.7)	32.4 (14.6–39.7)	≤0.001
Masuda ISI	10.72 (7.44–12.94)	8.64 (5.55–10.79)	≤0.001
Stumvoll early	1338.4 (1162.6–1466.3)	1012.3 (792.1–1180.1)	≤0.001
Stumvoll late	340.8 (310.8–354.8)	260.7 (212.3–294.8)	≤0.001

The levels were expressed as median (25%–75%); NGT: normal glucose tolerance; Glu120: OGTT 2-hour glucose; Ins30: serum insulin level at 30 minutes after an OGTT; Ins120: serum insulin level at 120 minutes after an OGTT; Masuda ISI: the Matsuda’s insulin sensitivity index.
