Figure 1. — Associations of solid fuel use and tobacco smoking with chronic liver disease mortality. Adjusted hazard ratios were stratified by age-at-risk, sex and study area and adjusted for education, household income, alcohol consumption, long-term heating fuel exposure, cooking stove ventilation, body mass index, prevalent diabetes, hepatitis B surface antigen status and length of recall period. The boxes represent hazard ratios, with the size inversely proportional to the variance of the logarithm of the category-specific log risk [which also determines the confidence interval (CI)], and the vertical lines represent 95% CIs. The numbers above the vertical lines are point estimates for hazard ratios (HRs), and the numbers below the lines are numbers of events. The analysis was restricted to individuals who had data on solid fuel use and smoking (n = 350 349).
