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: The growing use and public visibility of injectable weight-loss medications, including GLP-1 receptor agonists and related therapies, have raised important public health concerns regarding knowledge, attitudes, information sources, and safe use. This study assessed knowledge, attitudes, information sources, perceived social media influence, misconceptions, and self-reported use or consideration of weight-loss injections among adults in Al-Ahsa, Saudi Arabia, and examined associations with selected participant characteristics and BMI. Methods: This descriptive, cross-sectional study included 718 adults in Al-Ahsa, Saudi Arabia, and was conducted using an online structured questionnaire that was reviewed by experts and pilot-tested before the main data collection. Data were analyzed using the Statistical Package for the Social Sciences version 29. Descriptive statistics were used to summarize participant characteristics, knowledge, attitudes, information sources, perceived social media influence, and use patterns. Chi-square tests were used to examine associations between weight-loss injection use or consideration and selected participant characteristics. Results: Knowledge responses showed uncertainty regarding several aspects of weight-loss injections, particularly their mechanisms and potential adverse effects. Participants generally recognized the risks associated with unsupervised use, while perceptions regarding effectiveness and long-term safety were more varied. Overall, 8.5% of participants reported current or previous use of weight-loss injections, and 8.5% reported considering future use. Among users, tirzepatide was the most commonly reported injection (42.6%), followed by semaglutide (39.3%) and liraglutide (14.8%). Social media was the most frequently reported source of information (62.1%), followed by friends or family (41.5%) and healthcare professionals (39.1%). Use or consideration of weight-loss injections was significantly associated with age group, education level, and BMI category, but not sex. Conclusion: Adults in Al-Ahsa showed considerable uncertainty across several knowledge items and generally mixed perceptions regarding the effectiveness and safety of weight-loss injections, with relatively low current or previous use but emerging interest in future use.
