Dichotomised survival prediction models were generated using Lasso regression in 269 patients with malignant pleural mesothelioma
| Model 2 (survival <6 months) | Model 3 (survival <12 months) | ||||
| Optimal threshold: 0.3 | Optimal threshold: 0.6 | ||||
| False | True | False | True | ||
| False | 40 | 10 | False | 27 | 22 |
| True | 19 | 28 | True | 7 | 38 |
The performance of dichotomised predictions (rows) at selected optimal threshold values relative to the observed survival outcomes (columns) is reported in contingency tables.
