Observer | Method | mean 2D:4D (SD) | ∆ | TEM (%) | SEE | ICC (95% CI) | Classification |
---|---|---|---|---|---|---|---|
Observer 1 | RX | 0.905 (0.020) | 0.001 | 0.004 (0.6%) | 0.005 | 0.97 (0.94-0.98) | excellent |
DXA | 0.908 (0.019) | 0.001 | 0.006 (0.8%) | 0.009 | 0.90 (0.85-0.93) | excellent | |
Observer 2 | RX | 0.904 (0.020) | 0.001 | 0.006 (0.8%) | 0.010 | 0.91 (0.85-0.95) | excellent |
DXA | 0.907 (0.020) | 0.001 | 0.007 (0.9%) | 0.009 | 0.91 (0.85-0.94) | excellent |
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.
