Anthropometry, clinical pelvimetry, MRI, and kinect measurements and novel risk scores.

Model parameters (βo and βi) are for the model specified in Eq (1), with either Eq (2)1 or (2)2. Eq (2)1 was used for the clinical pelvimetry scores since these data were categorical. Eq (2)1 outperformed Eq (2)2 for the anthropometry risk score, whereas Eq (2)2 outperformed Eq (2)1 for the MRI and Kinect risk scores. The red bold-italic font denotes features that are statistically different (pAPD = anterior-posterior diameter, TD = transverse diameter, AC = abdomen circumference, OD = oblique diameter, PSD = posterior sagittal diameter, BPD = biparental diameter, OFD = occipitofrontal diameter, OMD = occipitomental diameter, SOBD = suboccipitobregmatic diameter, HC = head circumference, and AC = abdomen circumference.
