Table 2. Intra- and inter-rater reliability of the infrasternal angle measurement by the radiographic method (N=25)

Radiographic measurement	Intra-rater reliability	Inter-rater reliability
ICCs(3,1)	0.99	0.99
95% CI	0.98-0.99	0.98-0.99
SEM	1.13°	0.99°
MDD	3.13°	2.76°

ICC: intraclass correlation coefficients, CI: confidence interval, SEM: standard error of measurement, MDD: minimal detectable difference.
