Multiple logistic regression analysis of dizziness (VSS-SF), balance (VSS-V) and autonomic/anxiety-related symptoms (VSS-A) in N = 405 patients with complaints of dizziness examined in the period 1992–2001 in Bergen, Norway

^a VSS-SF: dichotomized at cut-off value ≤ 6.5, i.e. dizziness, yes/no

^b VSS-V: dichotomized at cut-off value ≤ 2.5, i.e. balance-related dizziness, yes/no

^c VSS-A: dichotomized at cut-off value ≤ 3.5 points, i.e. autonomic/anxiety-related dizziness, yes/no

^d OR: Adjusted odds ratio

^e CI: Confidence interval

^f P-value from likelihood ratio test
