Analyses were adjusted for educational level, income, alcohol intake, smoking
status, physical activity, survey season, and consumption of dairy products,
meat, and preserved vegetables and were stratified according to age at risk,
sex, and region. The black boxes represent hazard ratios, with the size
inversely proportional to the variance of the logarithm of the hazard ratio, and
the vertical lines represent 95% confidence intervals. The numbers above the
vertical lines are point estimates for hazard ratios, and the numbers below the
lines are numbers of events.
