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
  1. ATR- angle of trunk rotation, STR -surface trunk rotation, PPV -positive predictive value, NPV -negative predictive value.
