Table 2 Sensitivity, specificity, positive and negative predictive value of surface trunk rotation related to ATR ≥7°
From: School screening for scoliosis: can surface topography replace examination with scoliometer?
| ATR scoliometer | STR surface topography | SENSITIVITY [%] | SPECIFICITY [%] | PPV [%] | NPV [%] |
|---|---|---|---|---|---|
| ≥ 7° | ≥ 7° | 38.7 | 98.6 | 48.0 | 98.0 |
| ≥ 7° | ≥ 6° | 48.4 | 95.6 | 26.3 | 98.3 |
| ≥ 7° | ≥ 5° | 64.5 | 88.0 | 15.0 | 98.7 |
| ≥ 7° | ≥ 4° | 77.4 | 71.1 | 8.1 | 99.0 |
