Long-term health outcomes and cost-effectiveness of a computer-tailored physical activity intervention among people aged over fifty: modelling the results of a randomized controlled trial

Note: Differences in MET-hours between both measurements were calculated using the data including imputations for participants who dropped out; bold numbers reflect a significant difference between the intervention conditions of p<.05.
