Abbreviations: NHL = non-Hodgkin lymphoma, OR = odds ratio, CI = confidence interval, AOR = adjusted odds ratio, HBsAg = hepatitis B surface antigen, Anti-HBs = hepatitis B surface antibody, Anti-HBc = hepatitis B core antibody. The multivariate logistic regression analyses were adjusted by age (as a continuous variable), sex and year of diagnosis. * Statistically significant at the 0.05 alpha level. A: regard HBsAg-, anti-HBs-, anti-HBc- subgroup as reference. B: regard HBsAg-, anti-HBs+, anti-HBc + subgroup as reference
