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
Objectives Glaucoma is the major cause of irreversible blindness globally and ranks as the sixth leading cause of avoidable blindness in Cambodia. Recent advancements in glaucoma treatment techniques have emerged; yet, patient treatment preferences, particularly within low-resource environments, remain poorly understood. We are using the Health Belief Model (HBM) to identify factors that influence the preference for surgical versus medical therapy in adults with advanced glaucoma in Cambodia. Methods A hospital-based cross-sectional study was conducted at Preah Ang Duong Hospital, Phnom Penh, Cambodia, between January and June 2024. A structured, validated questionnaire evaluated sociodemographic characteristics, clinical data, glaucoma awareness, and HBM constructs (susceptibility, severity, benefits, barriers, self-efficacy, and cues to action). Logistic regression was used to determine the independent factors of surgical preference. Results Among the 487 participants, merely 138 of them (28.13%) favored surgical intervention. Patients who chose surgery had fewer perceived barriers, stronger perceptions of severity, susceptibility, benefits, and self-efficacy, and considerably higher knowledge scores (p=0.048). Multivariable analysis indicated that perceived benefits (AOR=1.51; 95% CI: 1.16-1.94), perceived severity (AOR=1.71; 95% CI: 1.17-2.51), low perceived barriers (AOR=0.61; 95% CI: 0.49-0.77), and high self-efficacy (AOR=1.46; 95% CI: 1.11-1.93) were independent predictors of surgical preference. Conclusion Psychological and contextual factors significantly influence treatment decisions among Cambodian patients with advanced glaucoma in our clinical setting. Enhancing knowledge, addressing misconceptions about surgery, and improving access to glaucoma services may increase acceptance of surgical intervention, promote better disease management, and subsequently help prevent blindness in our community.
