The colored boxes mark which categories the prevalence ratios concern, which in the multicategorical variable (model 7) are combinations of variables. Values are PR (prevalence ratios) with 99% CIs; AUC (area under the receiver operating characteristic curve) with 99% CI; ΔAUC (change in the AUC value compared with model 1).
