↵a Results are shown as absolute figures and percentages for qualitative variables, and as median and interquartile range for quantitative variables.
↵b Positive DHT is vertigo and nystagmus. Global positive DHT is vertigo and nystagmus, or vertigo only. DHT = Dix–Hallpike test. Interv = intervention.
