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: Increasing non-participation in research studies and high dropout rates in research on mental health apps compromise interpretability and generalizability of results. Analyzing underlying reasons holds promise for improving future recruitment methods, study design, and app features. Objective: This study investigated reasons for non-participation and dropout among adult psychiatric outpatients in a study examining an app for self-reflection, daily structuring, relaxation, mindfulness, and psychoeducation in Germany during COVID-19 pandemic, as well as potential differences between dropouts and completers. Methods: Descriptive statistics on reasons for non-participation using an anonymous questionnaire and for dropout based on semi-structured telephone interviews were performed. Differences between dropouts and completers in sociodemographic, clinical, app-related, and daily mood data were analyzed. Results: Of Conclusions: This study provides exclusive insights into non-participation and dropout in an app study among adults with mental disorders. It identified personal motivation, app-related aspects, no interest in app-based offers, and personal health complaints as common reasons. Suggestions for improving future studies include focusing on incentives, app questionnaires, app installation, user needs analysis, and symptom severity. Early app engagement and adherence measurements (for example number of daily mood reports) may help identify potential dropouts earlier in future studies.
