Two groups of measurement results under different varus angles
| Angle | T (n = 55) | t' (n = 55) | t−t' & 95%CI | P value | ||
|---|---|---|---|---|---|---|
| Mean ± SD (mm) | CV(%) | Mean ± SD (mm) | CV(%) | |||
| 5°(n = 11) | 2.1 ± 0.3 | 14.29 | 2.1 ± 0.3 | 14.29 | − 0.02 (− 0.3–0.2) | 0.9 |
| 10°(n = 11) | 4.1 ± 0.7 | 17.07 | 4.0 ± 0.6 | 15.00 | 0.01 (− 0.6–0.6) | 0.98 |
| 15°(n = 11) | 6.2 ± 1.1 | 17.74 | 6.3 ± 1.1 | 17.46 | − 0.07 (− 1.0–0.9) | 0.9 |
| 20°(n = 11) | 8.6 ± 1.3 | 15.12 | 8.5 ± 1.3 | 15.29 | 0.02 (− 1.1–1.1) | 0.97 |
| 25°(n = 11) | 10.4 ± 1.7 | 16.35 | 10.4 ± 1.7 | 16.35 | − 0.04 (− 1.6–1.5) | 0.96 |
CI = confidence interval; CV = coefficient of variation
