Table 4 Goodness-of-fit of observed comorbid disability weights and comorbid disability weights predicted with the three adjustment approaches, stratified by severity of the disease
Severity | Maximum limit approach ICC (95% CI) | Additive approach ICC (95% CI) | Multiplicative approach ICC (95% CI) |
|---|---|---|---|
Mild to moderate chronic disease (dw < 0.21) | .073 (-.269 - .401) | .399 (.073 - .649) | .351 (0.17 - .615) |
Severe chronic disease (dw ≥ 0.21) | .887 (.530 - .979) | .953 (.780 - .992) | .933 (.699 - .988) |
