Supplementary Material

Supplementary Figure 1. The model parameters (as sketched in Figure 2), that is, (a) cost of initial comorbidity in US dollars, (b) cost of onset in US dollars, (c) population recovery (slope) in 1/month, and (d) cost of acquired comorbidity in US dollars) estimated in specific groups (in the same sequence as in Tables 2–5): total (black, coincide with results in Figure 3), disability groups (red, the lower point, the higher disability), comorbidity group(blue, the lower point, the higher Charlson index), two age group (violet, <80, 80+), survival status (green, died or nor in 2.5 years after onset).

Supplementary Figure 2. Cohort specific estimates of model parameters (blue for 1994 and red for 1999).
