Participant flowchart. This chart illustrates the flow of participants through the trial and the response to the measurements. Analyses were performed for participants with either complete objective or complete subjective baseline- and follow-up data. Therefore the number of participants that was analysed in the completers-analyses is smaller than the number that responded to the follow-up measurements.
