  1. Stepwise backward linear and logistic regression analysis, bootstrap 1500x, α = .05. Variables selected in ≥1000 of the 1500 bootstrap samples were retained for the final models and highlighted in bold (indicators).
  2. Prev: prevalence in the research population; Bm: average regression weight over all bootstrap samples; Bs: regression weight in selected model; OR: Odds Ratio; CI: Confidence Interval. §OR is estimated per year increase or decrease.*Dichotomous DHI-scores: scores 0-30 (mild impact of dizziness) = 0, scores 31-100 (moderate or severe impact of dizziness) = 1.
