Unadjusted logistic regression analysis of dizziness according to the VSS-SF, vertigo/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. vertigo/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: Unadjusted odds ratio
^e CI: Confidence interval
^f P-value from likelihood ratio test
