Right thoracic curvature in the normal spine

Table 1 Intraobserver reliability analysis for the measurement of Cobb angle.

	Interclass correlation coefficient
Observer 1 (N = 12)	0.81 (0.67-0.90)
Observer 2 (N = 12)	0.61 (0.36-0.78)
Observer 3 (N = 12)	0.79 (0.63-0.88)

Each observer measured CT images (N = 12) and interclass correlation coefficient was calculated. Numerical value shows the gamma of interclass correlation coefficient and the range of the 95% confidence interval.
