The light intervention consisted of a step counter and a minimal version of the smartphone application. Patients randomised to the intensive intervention discussed PA barriers and goals, received a step counter, a patient-tailored smartphone application and supportive coaching calls. PA (primary outcome, assessed by an accelerometer), physical function, quality of life and symptoms were measured at baseline, after 3\u2009months (primary endpoint) and 1 year. Mixed model analyses were used to investigate the effectiveness of the intervention compared with the light intervention.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Between-group difference in change after 3\u2009months and 1 year was observed as mean (CI) 750 (\u221296 to 1596) (p=0.08) and 680 (\u2212244 to 1605) steps per day (p=0.15), 10 (\u22120.5 to 20) and 10 (\u22121 to 22)\u2009min of total moving time (walking, taking stairs and cycling) (both p=0.07) and \u22123 (\u22126 to 0) (p=0.07) and \u22126 (\u221210 to \u22122) (p=0.002) of sedentary time, all in favour of the intervention group.
