The “Diabetes Mellitus: Action Through Groups or Information for Better Control? » (D-Magic) study was a three-arm cluster randomised controlled trial conducted in four rural sub-districts of Faridpur, Bangladesh. The trial tested the impact of two interventions, participatory learning and action (PLA) and mHealth messages, in the prevention of T2DM. For this analysis, we used data from the D-Magic endline evaluation survey, which included interviews with 11,454 permanent residents, males and non-pregnant females, aged 30 years and older, conducted between January 16 and April 30, 2018.
