Figure 1

Estimated effects of age and calendar year for the multivariate models of HCV infection risk. WIHS: solid lines; UHS: dashed lines. Vertical bars are pointwise 95% confidence intervals. a) Estimated odds ratios for age. The reference age is 30, where the odds ratio is 1.0 by definition. b) Estimated odds ratios for calendar year. The reference year is 1975, where the odds ratio is 1.0 by definition.
