Evaluation of the increased predictive ability of the CONUT score for 1- year all-cause mortality when added to the VALID-CRT risk score
| Risk score | C-statistic (95% CI) | P value | NRI (95% CI) | P value | IDI (95% CI) | P value |
| VALID-CRT risk score | 0.63 (0.54 to 0.72) | Ref. | Ref. | Ref. | ||
| VALID-CRT risk score+ CONUT score | 0.78 (0.70 to 0.86) | 0.003 | 0.78 (0.45 to 1.12) | <0.001 | 0.12 (0.06 to 0.18) | <0.001 |
