Frequency per group is given in percentage and values of Fisher’s exact probability test obtained by intergroup comparison. Significant different values are indicated in bold numbers. HSN: head shaking nystagmus, SPN: spontaneous nystagmus in the dark, UW: unilateral weakness of caloric irrigation, DP: directional preponderance of caloric irrigation, vHIT: video-head-impulse test, LC: lateral SCC, AC: anterior SCC, PC: posterior SCC, SVV: subjective visual vertical, OT: ocular torsion.
