Gray LJ, Yates T, Troughton J, Khunti K, Davies MJ. Engagement, Retention, and Progression to Type 2 Diabetes: A Retrospective Analysis of the Cluster-Randomised "Let's Prevent Diabetes" Trial. PLoS Med.
Prevention of type 2 diabetes mellitus (T2DM) is a global priority. Let's Prevent Diabetes is a group-based diabetes prevention programme; it was evaluated in a cluster-randomised trial, in which the primary analysis showed a reduction in T2DM (hazard ratio [HR] 0.74, 95% CI 0.48-1.14, p = 0.18). We examined the association of engagement and retention with the Let's Prevent Diabetes prevention programme and T2DM incidence.
