  1. Prx: Pr(x=1), the probability of having a neighborhood attribute (e.g., having shops near home).
  2. Pry: Pr(y=1׀x=0), the probability of having the outcome (meeting physical activity recommendations) given that the neighborhood attribute is not present.
  3. Bolded numbers: statistical tests with >0.50 power based on post-hoc power analyses for logistic regression.
  4. Underlined numbers: associations that are close to statistical significance (0.05<p<0.1) with statistical power that is slightly below 0.50.
  5. a Could not be calculated due to the lack of variance in residential density.
