Estimated average linear growth curves for log MET-hours per week of leisure-time physical activity (a), log MET-hours per week of transport-related physical activity (b), and hours per week of overall sedentary time (c) separately for assessment-only group and intervention group. MET = Metabolic equivalent of task. Results were adjusted for sex, age, and education. Slope variances fixed to zero as indicated by likelihood ratio tests. To raise intuitive understanding, the outcome of sedentary time was re-calculated into hours per week
