Literature comparison of definitions of pelvic dimensions

Study	Pelvic width	Pelvic height	Pelvic depth
Seidel et al. [26]	Horizontal distance between ASISs	Perpendicular distance from pubic center to inter-ASIS line	Oblique distance between ASIS and PSIS
Current study	Horizontal distance between lateral edges of iliac wings	Vertical distance between top of iliac wing and bottom of ischial tuberosity	Direct horizontal distance between ASIS and PSIS

ASIS = anterior-superior iliac spine; PSIS = posterior-superior iliac spine.
