  2. OR – odds ratio; aOR1 – adjusted odds ratio for age; aOR2 – adjusted odds ratio for age and sex; CI – confidence interval.
  3. All results were significant at p < 0.001, except when noted (NS – not significant).
  4. The overall significance levels of the multiple logistic regression models were p < 0.001.
