  1. OR odds ratio, CI confidence interval, Exp. B exponent of B, POS public open space, ref reference category, min minutes, ° α < 0.1 = trend towards significance
  2. aThe logistic regression model estimated the association of the independent factors with the odds of having visited a POS
  3. bThe Gamma models (Exp. B) estimated the proportional difference in min spent in POS associated with a one-unit difference in the independent variables for adolescents that had visited a POS. Analyses were controlled for mean temperature, residence, POS visits/day, total wear time (mean min/day), and amount of days. All Gamma models were fitted using the log link function
