Logistic regression models of association of risk factors with esophageal cancer

Risk factor	Odds ratio	95%CI	P value
Isoprostane excretion (log)	2.35	1.19-4.65	0.014
Current/former smoker vs never	11.24	1.37-92.40	0.024
Current/former alcohol use vs never	2.49	0.744-8.34	0.140
HIV seropositive	3.450	0.656-18.14	0.140
Total fruits	0.761	0.542-1.07	0.110
Total vegetables	0.917	0.822-1.02	0.120
Total fish	0.364	0.108-1.23	0.100
Total animal products	0.555	0.162-1.90	0.350
Total insects	4.220	0.463-38.42	0.200

Associations between risk factors and cancer are presented as OR with 95%CI, and a P value of < 0.05 was required for statistical significance. HIV: Human immunodeficiency virus.
