Association between triglyceride-glucose index and colorectal polyps: A retrospective cross-sectional study

Table 3 Threshold effect analysis of triglyceride-glucose index on for the occurrence of colorectal polyps using a two-piecewise linear regression model

Colorectal polyps	Odds ratio (95%CI)	P value
TyG index
Fitting by standard linear model	1.55 (1.30, 1.86)	< 0.0001
Fitting by two-piecewise linear model
Inflection point	2.31
< 2.31	1.7 (1.40, 2.06)	< 0.0001
> 2.31	0.57 (0.27, 1.23)	0.1521
Log-likelihood ratio	0.009

Age, sex, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol were adjusted. TyG: Triglyceride-glucose.
