Comparison of the presence proportion of null point, and canal paresis between patients with HSC-Lcu and HSC-Hcu.

NP and CP	HSC-Lcu	HSC-Hcu	p value
NP1, n (%)	22 (42.3)	17 (36.2)	0.533
NP2, n (%)	48 (92.3)	47 (100)	0.052
NP3, n (%)	37 (71.2)	32 (68.1)	0.740
CPᵃ, n (%)	29 (65.9)	16 (37.2)	0.030*

^ᵃIn the caloric test, we finally included 44 patients with HSC-Lcu and 43 patients with HSC-Hcu. ^*p < 0.05. CP, canal paresis; HSC-Lcu, horizontal semicircular canal light cupula; HSC-Hcu, horizontal semicircular canal heavy cupula; n, number; NP1, the first null point; NP2, the second null point; NP3, the third null point.
