Predicted values for a single future measurement with 99% CI and total interval width*
| Rotation axis | Predicted value | Lower limit | Upper limit | Total |
|---|---|---|---|---|
| Preincision FFA1 | −2.5 | −11.5 | 6.6 | 18.1 |
| PCA-3 | −1.3 | −10.2 | 7.6 | 17.8 |
| Surgical TEA | −0.91 | −9.4 | 7.6 | 17 |
| Surgical TEA + preincision FFA1 | −1.7 | −9.3 | 6 | 15.3 |
| Combined | −1.6 | −8.8 | 5.6 | 14.4 |
| 2 cylinder | 1.9 | −4.3 | 8.1 | 12.4 |
| 1 cylinder | 2.8 | −2.4 | 8 | 10.4 |
* All values are in degrees; FFA1 = preincision functional flexion axis; PCA = posterior condylar axis externally rotated by 3°; TEA = transepicondylar axis.
