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
Background: Unhealthy dietary habits such as high-sodium intake, are socially embedded and often resistant to individual-level interventions. Family-led approaches, where 1 member initiates change within the household, may offer a more effective alternative. Objectives: This pilot study assessed the feasibility and preliminary impact of a digitally delivered, young adult-led sodium reduction intervention on household-level knowledge, attitudes, and behaviors in Singapore. Methods: In a pre-post, single-group design, young adults completed a co-created, self-paced online course featuring video lessons, interactive assignments, and personalized feedback. Over 2 weeks, participants developed sodium-reduction goals and implemented them through tailored 4-wk action plans. Weekly reflections and course metadata captured goal progress, effort, strategies, and barriers. Family members completed parallel preintervention and postintervention surveys, although they did not receive the intervention directly. Surveys assessed constructs from the Theory of Planned Behavior. Multivariable linear mixed models evaluated changes over time, adjusting for demographic and health characteristics. Results: Overall, 35 young adults (mean age: 24.4 y; standard deviation [SD]: 3.1) and 79 family members (mean age: 43.0 y; SD: 15.5) completed the intervention. Young adults took a mean of 7.7 d to complete the course, with most crafted goals focusing on reducing sodium intake when eating out. Participants reported higher effort and success with personal goals than family-oriented ones. Perceived behavioral control showed the greatest improvement among both young adults (+2.64, 95% confidence interval [95% CI]: 2.05, 3.22) and family members (+1.82, 95% CI: 1.42, 2.22). Significant gains were also observed in knowledge, behaviors, subjective norms, and behavioral intentions for all participants (all Conclusions: A young adult-led, family-focused digital intervention was feasible and demonstrated preliminary improvements in household sodium-related outcomes, warranting further evaluation in larger, more diverse populations.
