The problem
Intervention: Time-restricted eating with a 12-hour eating window, with or without a fixed last meal time of 8 PM
Who it was tested with: 192 children and adolescents with elevated blood pressure, aged range not specified, enrolled from two schools.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"We conducted a 12-month, three-arm cluster-randomized controlled trial in two schools, with classes as the unit of randomization (91 classes)... A total of 192 participants were enrolled and analyzed under an intention-to-treat framework." The study used random allocation to intervention and control groups with a cluster design, meeting criteria for experimental design despite the high attrition.
High attrition rate (40.6% loss-to-follow-up by 12 months) undermines confidence in results. The study does not report adherence rates to the eating windows, potential adverse effects, or mechanisms of change. Multiple imputation was used as sensitivity analysis but results are not detailed.
