Table 4 Adjusted logistic regression for the CFS and HFRS*
Outcome | CFS categories (by original categories) | Adjusted OR (95% CI) | CFS categories (by combined non-frail and mild frailty categories) | Adjusted OR (95% CI) | HFRS categories (by original categories) | Adjusted OR (95% CI) |
|---|---|---|---|---|---|---|
30-day mortality | Non-frail (1–3) | 1.00 | Non & mild frailty (1–5) | 1.00 | Low risk frailty (< 5) | 1.00 |
