All analysis is done as ITT. P-values after test 1–3 show results within the two groups over time and are done using Pearson´s x² test and Student´s t-test. P-value to the right shows the Intervention group* Test round effect. ANCOVA analysis is performed. Due to missing data, the number of responders on the different measures varies from 37–54 in intervention and 24–44 in reference group.
