Intraclass correlations coefficients (ICC) and the 95% confidence interval for the intraobserver analysis and interobserver measurement
| Intraobserver (n = 9) | Interobserver (n = 9) | |||||
|---|---|---|---|---|---|---|
| Outcome measure | ICC | 95% Confidence interval | Absolute difference | ICC | 95% Confidence interval | Absolute difference |
| Inclination angle TalusIF | 0.994 | 0.944–1 | 0.46 ± 0.39 (0.05‐1.28) | 0.989 | 0.953–0.998 | 0.71 ± 0.85 (0.04‐2.18) |
| Deviation angle TalusIF | 0.981 | 0.821–1 | 0.48 ± 0.36 (0.05‐1.03) | 0.988 | 0.949–0.997 | 1.27 ± 1.07 (0.24‐3.08) |
| Radius TalusSF | 0.969 | 0.792–0.999 | 0.08 ± 0.05 (0.03‐0.17) | 0.977 | 0.828–0.990 | 0.29 ± 0.19 (0.03‐0.59) |
| Radius TalusIF | 0.994 | 0.952–1 | 0.25 ± 0.17 (0.00‐0.59) | 0.985 | 0.932–0.996 | 0.49 ± 0.36 (0.06‐1.12) |
Note: Also, the average ± 1 SD and range (minimal–maximal) of the absolute differences are presented for the intra‐ and inter‐observations. TalusSF: cylinder of superior facet of the talus. TalusIF: cylinder of posteroinferior facet of the talus. Absolute differences angles in degrees, and radius in mm.
