Table 1.
Lin’s Concordance Correlation Coefficient (CCC) of 12 angles for both measurement methods, ground and BalancAid, resulted that angle a, c, e, f, g, i, and k in PA view and angle m and q in LA vier give higher reproducibility
| Angle | CCC ground | CCC BalancAid | p-Value based on the comparison of the two mixed effects models |
|---|---|---|---|
| PAa | 0.884 | 0.895 | 0.4744 |
| PAb | 0.909 | 0.895 | 0.0528 |
| PAc | 0.898 | 0.909 | 0.4133 |
| PAe | 0.907 | 0.922 | 0.2089 |
| PAf | 0.946 | 0.952 | 0.3369 |
| PAg | 0.931 | 0.944 | 0.0877 |
| PAi | 0.847 | 0.874 | 0.0893 |
| PAj | 0.889 | 0.878 | 0.1715 |
| PAk | 0.927 | 0.937 | 0.1913 |
| LAm | 0.710 | 0.904 | 0.0001 |
| LAo | 0.761 | 0.715 | 0.4973 |
| LAq | 0.750 | 0.830 | 0.0675 |
Angle m has a significant difference in concordance between both methods in two-day measurements
