Dutch Clinical Prediction Rule (DCPR): predicted probability of ambulation by selected scores
| DCPR Score | Predicted probability of independent ambulation at 1 year (%) |
|---|---|
| − 10 | < 1 |
| − 5 | 1 |
| 0 | 4 |
| 2 | 6 |
| 5 | 13 |
| 10 | 35 |
| 15 | 68 |
| 20 | 89 |
| 25 | 97 |
| 28 | 99 |
| 30 | > 99 |
| 35 | 100 |
| 40 | 100 |
Predicted probability of independent ambulation corresponding to various DCPR scores. See Table 2 for method of calculation of DCPR score. Predicted probabilities are calculated based on the following model
Predicted probability = EXP(− 3.273 + 0.267 × DCPR − score)/(1 + EXP[− 3.279 + 0.267 × DCPR − score])
Point estimates for example cases A and B from Table 2 are given
