Validity of readmissions using process indicators as the gold standard for patients with heart failure (N = 1055)
| Indicators | Sensitivity (95% CI) | Specificity (95% CI) | Positive predictive value (95% CI) | Negative predictive value (95% CI) | Positive likelihood ratio | Negative likelihood ratio |
