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.

2 · The registry

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

Objective: Behavioral science principles, including approaches such as gamification, commitment strategies, and nudges, are widely used in health promotion programs to prevent non-communicable diseases. These approaches are expected to influence behavior change regardless of health interest; however, their effectiveness remains unclear. This study evaluated the impact of a behavioral science-based health promotion program on body mass index (BMI) reduction across different levels of health interest. Methods: This study evaluated the "Checkup Championship," a program that applies various behavioral science strategies to improve health checkup results for employees at Hakuhodo DY Group in Japan. Participants in the program in 2020 were compared with non-participants. Health interest was classified as low, middle, or high based on a single-question assessment. A linear regression model analyzed BMI changes between 2019 and 2020, using the inverse probability weighting of propensity scores to adjust for background differences between groups. Results: A total of 410 participants and 390 non-participants were included in the study. BMI reduction was greater among participants than non-participants (-0.36 kg/m Conclusions: The "Checkup Championship" demonstrated effectiveness, particularly among individuals with a lower health interest. Health programs incorporating diverse behavioral science strategies may help reduce health disparities.
