Numerical values for each parameter of the clinical index adopted in the study
| Clinical parameter |
Score |
||
| 1 | 2 | 3 | |
| General conditions | Poor | Intermediate | Good |
| Pulse (beats/min) | > 110 | 90-110 | < 90 |
| Systolic blood pressure (mmHg) | < 90 | 90-110 | > 110 |
| Haemoglobin levels (g/dL) | ≤ 8 | 9-10 | > 10 |
The T-score is the sum of the corresponding values for the 4 parameters. In detail, a sum ≤ 6 corresponds to T1 (high-risk), 7-9 to T2 (intermediate-risk), and a cumulative value ≥ 10 to T3 (low-risk).
