Observer | RX mean (SD) | DXA mean (SD) | ∆ | TEM (%) | SEE | ICC (95% CI) | Classification |
---|---|---|---|---|---|---|---|
Observer 1 | 0.905 (0.020) | 0.908 (0.019) | 0.003 | 0.009 (1.2%) | 0.010 | 0.89 (0.83-0.93) | very good |
Observer 2 | 0.904 (0.020) | 0.907 (0.020) | 0.003 | 0.011 (1.4%) | 0.010 | 0.81 (0.74-0.87) | very good |
Note: Intrarater reliability (repeatability) for both raters. = difference; TEM = technical error of measurement, absolut and in % of the mean . SEE = standard error of estimate; ICC = intraclass correlation coefficients; CI = confidence intervall; classification according to Rosner (2011). ICCs < 0.7 were considered non-acceptable, 0.71 < ICCs < 0.79 were acceptable, 0.80 < ICCs < 0.89 were very good and ICCs >0.90 were excellent.
