Obesity as a risk factor for early-onset colorectal cancer: Evidence from a nationally representative database

Table 4 Independent contributions of body roundness index, body mass index, and waist circumference to early-onset colorectal cancer risk

Variable	BRI + BMI model		BRI + waist model		BRI + BMI + waist model
	OR	P value	OR	P value	OR	P value
BRI quartile 2	4.61	0.106	4.02	0.024	3.95	0.158
BRI quartile 3	6.47	0.097	3.92	0.082	4.76	0.199
BRI quartile 4	16.04	0.018	7.7	0.007	11.7	0.053
Obese (BMI)	0.62	0.64			0.6	0.615
Overweight (BMI)	1.05	0.96			1.07	0.936
Obese (waist)			1.34	0.608	1.46	0.506

We assessed the significant of body roundness index across 3 different models (model 1 body roundness index + body mass index; model 2 body roundness index + waist; and model 3 body roundness index + body mass index + waist). P < 0.05 were considered as significant value. BRI: Body roundness index; BMI: Body mass index.
