  1. 1. Each variable is controlled for the other ones in the table plus self-reported health status and activities in daily living using conditional logistic regression.
  2. 2. P-values for each variable category compared to the reference level.
  3. Model fit statistics: McFadden's R2 = 0.297, McFadden's Adj R2 = 0.206, Count R2 = 0.777, Likelihood-ratio χ2 (14 df) = 91.485, p < 0.001
