A new sagittal parameter to estimate pelvic tilt using the iliac cortical density line and iliac tilt: a retrospective X-ray measurement study

Table 3 The intraobserver reliability analysis for the measurement of the IT. Each observer measured the IT (N = 12) and the interclass correlation coefficient was calculated. The numerical value shows the gamma of the interclass correlation coefficient and the range of the 95 % confidence interval

	Interclass correlation coefficient
Observer 1 (N = 12)	0.89 (0.79–0.94)
Observer 2 (N = 12)	0.87 (0.76–0.93)
Observer 3 (N = 12)	0.87 (0.77–0.93)
