^a The probability (odds ratio) of walking from baseline to 2, 6 and 12-month follow-up. The data were coded dichotomously to zeros (=0, no walking) and nonzeros (=1, walking).

^b Logarithm-transformed nonzero responses. Worksite included as a random effect (intercept) and gender, taking care of minors (yes/no), age (continuous) and body mass index at baseline (continuous) as covariates.

^c Untransformed values.
