Correlation coefficients between JB position and angles between ipsilateral semicircular canals

Plane	JB–Psag		JB–Pcor		JB–Pfrkt
	L	R	L	R	L	R
∠ipsiA/ipsiH	–0.22	–0.19	–0.08	–0.07	0.06	–0.01
∠ipsiP/ipsiH	–0.21	–0.04	0.15	–0.26*	0.07	0.01
∠ipsiA/ipsiP	0.10	0.01	0.03	–0.14	0.16	–0.14

JB, jugular bulb; Psag, median sagittal plane; Pcor, coronal plane; Pfrkt, Frankfurt horizontal plane; L, left; R, right; ipsi, ipsilateral.

∠ indicate angle between 2 planes; A, H, and P indicate the anterior, horizontal, and posterior semicircular canal plane, respectively; JB–Psag, JB–Pcor, and JB–Pfrkt: The JB position in the cranial base was defined as its distances from Psag, Pcor, and Pfrkt planes, respectively.
