Tailored video-based lifestyle intervention for overweight or obese adults in Phnom Penh, Cambodia: a pilot cluster randomized controlled trial.
Trial report in Health policy and planning, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Physical activity plays a crucial role in preventing and managing obesity and its related comorbidities, with minimal side effects. Similarly, consuming a balanced diet is essential for maintaining good health and adequate nutrition. However, most adults fail to meet population-based dietary and physical activity guidelines. In this pilot cluster-randomized controlled trial, we aimed to evaluate the effectiveness of a video-based physical activity and dietary intervention among adults aged 30-59 years in Phnom Penh, Cambodia. A total of 63 adults participated in the 12-week program, with 31 assigned to the intervention group and 32 to the control group. The intervention group received a video-based program delivered via Telegram and YouTube, complemented by a 2-h in-person session focusing on technical orientation and safety training. Standard care was provided to both the intervention and control groups and consisted of a single 60-min in-person lifestyle education session and a printed booklet commonly used in Cambodian health center settings. The intervention group demonstrated greater improvements in physical activity adherence, healthy eating adherence, exercise self-efficacy, healthy eating self-efficacy, systolic blood pressure, body weight, body mass index, waist circumference, fasting blood glucose, and high-density lipoprotein cholesterol levels compared with the control group (P < .05). Given its high accessibility and ease of implementation, video-based content appears to be an effective approach and policy for improving health behaviors, even in resource-limited settings. These findings support the use of video and digital platforms as potential strategies and evidence-based policy for preventing and managing non-communicable diseases in low-resource settings. Trial registration ISRCTN11839050 (retrospectively registered).
