Randomization
All patients were provided oral and written information about the study at a visit by a research nurse and those who agreed to participate provided consent. The randomization procedure (block randomization) was conducted by an external organization outside the research group (Karolinska Trial Alliance, KTA) to avoid selection bias by anonymising the patient ID. Due to the nature of the intervention, it was not possible to conceal the participants' group allocation to neither patients nor researchers involved. However, the participants' allocation to intervention or control groups was masked in the dataset available for researchers during data analysis. Half of the eligible patients were randomized to intervention with home‐based exercise and half to standard care (control group).
