Forest plot showing the association of baseline, occupational and non-occupational risk factors with seropositivity based on multivariable logistic regression analysis. For this analysis, variables from Table 2 were dichotomized and combined into an additive model. Adjusted odds ratios (aOR) were derived from model coefficients, and 95% CI were obtained though the profile likelihood. See Table S3 for further details on model definition.
