Points assigned to each variable in the parsimonious mortality model according to their regression coefficient
| Variables . | Points . |
|---|---|
| Age >70 | 1 |
| ppoFEV1 <70% | 1 |
| Male gender | 2.5 |
| BMI <18.5 kg/m2 | 2.5 |
| Thoracotomy (as opposed to MITS) | 2.5 |
| Pneumonectomy (as opposed to lesser resections) | 3 |

| Male gender | 2.5 |
| BMI <18.5 kg/m2 | 2.5 |
| Thoracotomy (as opposed to MITS) | 2.5 |
| Pneumonectomy (as opposed to lesser resections) | 3 |
Numeric variables were categorized using ROC analysis.
BMI: body mass index; MITS: minimally invasive thoracic surgery; ppoFEV1: predicted postoperative forced expiratory volume in 1 s.
