Interexaminer variability of methods of craniocervical junction evaluation*
| Method | Shrout-Fleiss Reliability |
|---|---|
| BAI | 0.54 |
| BDI | 0.84 |
| Powers ratio | 0.87 |
| ADI | 0.65 |
| AOI | 0.77 |
Note:—BAI indicates basion-axial interval; BDI, basion-dens interval; ADI, atlantodental interval; AOI, atlanto-occipital interval.
* Value of 1 represents maximum reliability.
