Statistical results of intraobserver and interobserver measurement for superimposition of conventional and CAD/CAM occlusal splints.
| Intraobserver (operator A) | Mean ± SD | Minimum | Maximum | Pearson correlation coefficient (r) |
|---|---|---|---|---|
| 1st operation | 0.21 ± 0.05 | 0.25 | 0.32 | 0.987 |
| 2nd operation | 0.20 ± 0.07 | 0.27 | 0.31 | |
| Interobserver | Mean ± SD | Minimum | Maximum | Cronbach's alpha |
| 1st operation | 0.21 ± 0.05 | 0.25 | 0.32 | 0.972 |
| Operator B | 0.28 ± 0.11 | 0.22 | 0.38 | |
| 2nd operation | 0.20 ± 0.07 | 0.27 | 0.31 | 0.905 |
| Operator B | 0.28 ± 0.11 | 0.22 | 0.38 | |
Correlation coefficient (r) > 0.8, Cronbach's alpha > 0.8: the degree of linear relationship showed strong correlation.
