ObjectiveTo evaluate the effectiveness of telemedicine-delivered diet and/or exercise interventions to prevent type 2 diabetes (T2D) in people at risk. MethodsEmbase (via Ovid), Medline (via Ovid), Web of Science, CINAHL, Scopus and SciELO were searched from January 2010-December 2020 for intervention studies using a diet and/or exercise intervention delivered through telemedicine for T2D prevention in people at risk. Parallel randomised controlled trials were meta-analyzed and other intervention designs narratively synthesised. ResultsWe identified 11,645 studies via database searches, of which 226 were full text screened, and 52 interventions included; 32 were included in the meta-analysis and 20 in the narrative synthesis. Telemedicine interventions reduced body weight (mean difference (MD): -1.66 kg, 95% confidence interval (CI) -2.48,-0.90, I2=81%, nstudies=17), body mass index (MD -0.71 kg/m2, 95% CI -1.06,-0.37, I2=70%, nstudies=11), waist circumference (MD -2.82 cm, 95% CI -5.16,-2.35, I2=84%, nstudies=7) and HbA1c (MD -0.07%, 95% CI -0.14,0.00, I2=71%, nstudies=11). No significant effects were found for other clinical outcomes. The narrative synthesis supported the results. ConclusionsOur study highlights the potential for telemedicine-delivered interventions in preventing T2D in people at risk.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
