| HF hospitalization | | | | | | Low response score | 219 | 92 (42.0) | 1.00 | | | Medium response score | 129 | 24 (18.6) | 0.89 | 0.51 to 1.55 | 0.679 | High response score | 39 | 3 (7.7) | 0.29 | 0.09 to 0.99 | 0.048 |
| All-cause death | | | | | | Low response score | 219 | 81 (36.9) | 1.00 | | | Medium response score | 129 | 21 (16.3) | 0.29 | 0.09 to 0.99 | 0.179 | High response score | 39 | 1 (2.6) | 0.11 | 0.01 to 0.79 | 0.028 |
