The consistency of MRI-based pelvimetry between two radiologists.

MRI-based pelvimetry	Mean ± SD (range)	ICC (95% CI)	CV (%)	Bias (LoA)
Pelvic inlet	82.3 ± 9.8 (61.2–116.2)	0.973 (0.961 to 0.981)	2.861	−0.787 (−7.158 to 5.585)
Pelvic depth	125.8 ± 14.1 (94.5–158.8)	0.974 (0.962 to 0.982)	2.741	−1.698 (−10.699 to 7.302)
Pelvic outlet	118.1 ± 11.6 (73.1–148.7)	0.963 (0.947 to 0.974)	2.751	−1.281 (−9.968 to 7.406)
Transverse diameter	128.5 ± 8.1 (108.7–145.7)	0.925 (0.893 to 0.948)	2.533	−1.364 (−10.015 to 7.288)
Interspinous distance	98.9 ± 9.9 (78.4–126.0)	0.968 (0.953 to 0.977)	2.743	−1.442 (−8.437 to 5.553)
Intertuberous distance	114.6 ± 13.0 (81.9–144.1)	0.979 (0.970 to 0.985)	2.489	−1.524 (−8.878 to 5.830)

ICC, intraclass correlation coefficient, between two observers; CI, confidence interval; CV, coefficient of variation; LoA, limit of agreement.
