ORs and 95% CIs for the risk of incident HCC based on baseline serum AFP level and the level of AFP after genetic correction (per 10 ng/mL increase) in elderly Chinese people

Model	OR	95% CI	P
AFP level
Model 1	4.70	2.48–8.90	<0.001
Model 2	4.55	2.34–8.85	<0.001
Model 3	5.04	2.46–10.30	<0.001
Genetic corrected AFP level
Model 1	5.05	2.58–9.91	<0.001
Model 2	4.85	2.41–7.79	<0.001
Model 3	5.34	2.57–11.13	<0.001

Model 1, univariate model.

Model 2, adjusted for age, gender, smoking status, drinking status.

Model 3, adjusted for the variables in model 2 plus education, marriage, BMI, physical activity, family history of cancer.

AFP, alpha‐fetoprotein; BMI, body mass index; HCC, primary hepatocellular carcinoma; OR, odds ratio; 95% CI, 95% confidence interval.
