Table 2 Summary of unadjusted Logistic regression results

	OR	Std. Error	P value	95%CI (lower)	95%CI (upper)
BRI quartile 2	14.23	4.49	< 0.011	2.64	1.42
BRI quartile 3	17.73	5.03	< 0.012	3.23	1.42
BRI quartile 4	31.84	10.12	< 0.001	3.22	5.92
Obesity (BMI)	12.55	4.77	< 0.002	2.36	1.81
Overweight (BMI)	10.99	4.03	< 0.006	2.06	1.48
Obese (waist)	7.86	3.62	0.001	1.43	1.67

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