Mean predicted and observed disability weights by age bins. Predictions are carried out using equation 1, where the disability weight given to each condition is that of the mean condition-specific weight as estimated by the model. If the mean weight was negative, the condition weight was truncated to zero, as negative weights are not compatible with the multiplicative comorbidity equation. Each respondent was also given a baseline disability of 0.015, the model estimated intercept
