Regression coefficient (b) and 95% confidence interval (95% CI) from Generalized Linear Models with robust sandwich estimators to account for clustering; models use γ-variance function and identity link function (for minutes of walking for transport), negative binomial variance function and logarithmic link function (for sessions of walking for transport), and Gaussian distribution function and identity link function (for perceived destinations)
