Table 4
Sensitivity and specificity for the regression model and LACE indices greater than 10 and 6.
| Model | Readmitted ( = 572) | Not readmitted ( = 5290) | Sensitivity | Specificity |
| LACE index with cut-off of 10 | | | | | Lower risk | 519 | 5068 | 9.3% | 95.8% | Higher risk | 53 | 222 | LACE index with optimal cut-off of 6 | | | | | Lower risk | 193 | 2820 | 66.3% | 53.3% | Higher risk | 379 | 2470 | Regression model using variables available early in the admission with optimal cut-off | | | | | Lower risk | 221 | 3190 | 61.4% | 60.3% | Higher risk | 351 | 2100 |
