Rim area repeatability coefficients obtained with different types of HRT at different image sequences
| HRT type | Rim area repeatability coefficients (mm2) | |||
|---|---|---|---|---|
| I | II | III | IV | |
| I = intraobserver/intravisit; II = interobserver/intravisit; III = intraobserver/intervisit; IV = interobserver/intervisit. | ||||
| Low coefficient values equate to high repeatability; the difference of two measurements were within this value in 95% of cases. | ||||
| HRT Classic | 0.21 | 0.29 | 0.19 | 0.24 |
| HRT Explorer | 0.28 | 0.31 | 0.30 | 0.26 |
| HRT-II Explorer | 0.28 | 0.34 | 0.24 | 0.23 |
