Figure 2
Odds ratios (95% confidence intervals) for age-related macular degeneration comparing the 90th (2.17 μg/l) with the 10th percentile (0.61 μg/l) of the blood cadmium distribution. Cadmium was modeled as log-linear term. Multivariable logistic regression models were adjusted for age, sex, smoking status, and alcohol drinking. The size of the square is proportional to the sample size in each stratum. P-values correspond to tests for interaction between cadmium splines and selected participant characteristics.
