Associations of TG/HDL Ratio with the Risk of Prediabetes and Diabetes in Chinese Adults: A Chinese Population Cohort Study Based on Open Data

Table 3

Threshold effect analysis of TG/HDL on incident impaired glucose tolerance.

Outcome	Impaired glucose tolerance
	HR (95% CI)	value
One-line linear Cox regression model	1.04 (1.02, 1.06)	<0.001
Two-piecewise linear Cox regression model
TG/HDL < 1.04	1.57 (1.42, 1.73)	<0.001
TG/HDL ≥ 1.04	1.00 (0.98, 1.02)	0.9558
The effect of 2 and 1 is different	0.64 (0.57, 0.71)	<0.0001
Likelihood ratio test	<0.001
