Statistically significant differences were found for all measurements in all 3-dimensional planes between genders, with female patients having significantly reduced surgical S1 and S2 corridors than male counterparts. See text for abbreviations and explanations.
Abbreviations: S1FAC and S2FAC = S1 and S2 foramen-anterior cortex
TS1BHT and T2SBHT = tallest coronal S1 and S2 body height/the sagittal S1 and S2 mean body height
SS1BHT and SS2BHT = smallest S1 and S2 body height
S1SAG.mean and S2SAG.mean = S1 and S2 sagittal mean height
Angle 1A/2A and 1C/2C = axial S1 and S2 angle and coronal S1/S2 angle
