  1. INT, standard intervention group; INT-DPM, intervention group with diabetes prevention mentors (DPM); combined intervention, both intervention groups combined; CONTROL, control arm without trial intervention; Adjusted, analysis corrected for baseline HbA1c and imputed for missing data. The Combined INT vs CONTROL comparison is a post hoc analysis
