Both groups showed significant increases in the total
Voorrips scores, with higher values at 1-year than at
admission (intervention group: 4.1, p < 0.001; usual care
group 1.4, p < 0.001). Also, subgroup comparisons
revealed a significant difference after one year with higher
scores for the intervention group (2.7 (95% CI: 1.1e4.3
units)). Given that a large majority of patients forgot to
keep track of their daily physical activity in their diary, we
did not analyze this data.
