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: Multicomponent exercise is widely recommended to prevent and delay frailty. Despite the health benefits of exercise, participation in and adherence to exercise among community-dwelling frail older adults remain suboptimal. Aim: To develop a nurse-led mobile health-based nudging intervention program to support exercise behavior among community-dwelling frail older adults. Methods: This intervention development study was informed by the Guidance for Reporting Intervention Development Studies in Health Research checklist. The study comprised four sequential development phases followed by digital translation for delivery: scoping review, semi-structured interviews, theory-informed development, and structured expert consultation. The finalized intervention program was then translated into digital delivery. Results: A 12-week nurse-led mobile health-based nudging intervention was developed. The intervention program was grounded in the Capability, Opportunity, Motivation-Behavior model and targeted frail older adults' physical and psychological capability, physical and social opportunity, and reflective and automatic motivation for exercise. Fourteen nudge strategies were mapped to intervention components, including priming, information support, simplification, default options, emotional anchoring, feedback, expert authority, environmental cues, social norms, precommitment, framing, reminders, peer comparison, and gamification. These strategies were operationalized into intervention components, including technical guidance, health education, exercise lessons, future self-visualization, psychological adaptation, environmental modification, professional support, peer support, self-monitoring, goal setting, framing reminders, role modeling, and gamification. The final program specifies behavioral targets, nudge strategies, intervention content, delivery stages, and delivery platforms. Conclusion: The program was developed through a theory-, evidence-, participant-, and expert-informed process and may provide a structured intervention prototype for supporting exercise behavior among community-dwelling frail older adults. As this was a multiphase intervention development study, future pilot studies and randomized controlled trials are needed to evaluate implementation feasibility, user acceptability, intervention effectiveness, and optimal combinations of nudge strategies.
