Roles of GMRCs during the large-scale cohort study of the ToMMo. For the ToMMo, 120,000 of 150,000 participants enrolled in the TMM study were recruited via face-to-face consent and baseline assessments were carried out in FY 2013–2016. A secondary assessment, “TMM Repeat Assessment Center-based Survey during the Second Period”, was then commenced in FY 2017, to be continued until FY 2020. Requirements of each stage of the study are shown in green, while essential roles of the ToMMo GMRCs are indicated below in magenta
