Variable	OR	Std. Error	P value	95%CI (lower)	95%CI (upper)
BRI quartile 2	4.1	2.29	< 0.012	1.37	12.26
BRI quartile 3	4.36	2.64	< 0.015	1.33	14.31
BRI quartile 4	9.74	5.52	< 0.0001	3.2	29.6
Obesity (BMI)	4.26	2.02	< 0.002	1.68	10.8
Overweight (BMI)	3.75	1.81	< 0.006	1.46	9.67
Obese (waist)	1.14	0.37	0.002	0.41	1.86

We compared body roundness index quartiles to waist and body mass index while adjusting for smoking and heavy drinking. P < 0.05 were considered as significant value. OR: Odds ratio; 95%CI: 95% confidence interval; BRI: Body roundness index; BMI: Body mass index.
