RECRUITMENT, RECRUITMENT
Recruitment of participants took place from January 2020 to July 2020. During this period, 257 interested individuals registered for the clinical substudy. After screening (telephone interview and preliminary examination), 153 subjects were included in the study, and they completed the baseline measurement. There were 35 dropouts throughout the study. None of the health reasons of the dropouts were associated with the intervention. Since 4 study subjects did not attend the t2 examination due to the COVID-19 pandemic, they could not be included in the PP analysis (complete cases). The study participant flow is shown in Flow chart depicting participant recruitment and dropout. t2: 6-month follow-up.Baseline (t0) characteristics of the study participants.
