Coordinates of the curve for preoperative LAD values - sinus rhythm in the first month.
| Coordinates of the curve: | ||
|---|---|---|
| Positive if greater than or equal toa | Sensitivity | 1 - Specificity |
| 45.5000 (cutoff value) | 0.721 | 0.421 |
Test results: Preoperative LAD had at least one tie between the positive actual state group and the negative actual state group.

The smallest cutoff value is the minimum observed test value minus 1, and the largest cutoff value is the maximum observed test value plus 1. All the other cutoff values are the averages of two consecutively ordered observed test values.
