Kappa coefficients for inter-observer reliability in determining end vertebrae between manual measures and computer-aided measures

Parameters	%Agreement	Kappa
LEV lumbar	N/A	N/A
UEV lumbar	38.10	0.20
LEV thoracic	32.30	0.08
UEV thoracic	31.90	0.03
LEV cervical	15.30	0.00
LEV thoracic	19.70	0.04

Computer-aided measures always use S1 endplate

LEV lower end vertebrae; UEV upper end vertebrae
