1 · What the graph read from it

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.

Abstract

backgroundLifestyle modification is fundamental for obesity management but remains challenging. PURPOSE: To test the effectiveness of a 12-week digital self-regulation program on improving weight loss and self-regulation among young adults.

methodsA 2-arm parallel 1:1 randomized controlled trial was conducted. Participants were randomly assigned to either the intervention or the control group. The primary outcomes were weight and self-regulation, while the secondary outcomes were nutrition knowledge, eating phenotypes, overeating habits, anxiety, and depression. All data were collected at weeks 0, 12, and 24.

resultsWe showed the effectiveness of a digital commitment device on body weight (-1.90 ± 6.4 kg, P = .002), body mass index (-0.45 ± 2.0 kg/m2, P = .002), waist circumference (-2.10 ± 12.1 cm, P = .01), basal metabolic rate (-20.30 ± 118.6 kcal, P = .04) and body roundness index (-0.17 ± 0.6, P = .014). Interventional effects were sustained for waist circumference (-0.8 ± 2.8 cm, P = .05) and body roundness index (-0.07 ± 0.36, P = .047) 3 months beyond removing access to the commitment device. General improvements in nutrition knowledge, psychological flexibility, uncontrolled eating, and anxiety were found among both groups, but differences were only significant for depression scores (-0.06 ± 1.5, P = .032) and eating self-regulation (0.16 ± 0.54, P = .003).

conclusionThis study showed the potential of a digital commitment device in improving eating self-regulation, anthropometry, and mental wellness for scalable implementation in the community setting.
