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
purposeThis study was done at the Outpatient Department (OPD) of The National Hospital of Sri Lanka to explore how the increasing prevalence of digital screen usage has raised concerns regarding its effects on the eye, particularly among vicenarians.
methodsThe study was conducted as a descriptive correlational study, including 320 patients who were aged 20-30 years, and attended the Outpatient Department of National Hospital Sri Lanka; A self-administered questionnaire was used to assess and evaluate knowledge and attitude regarding increasing screen hours and effects on eye among patients. Descriptive statistics, including frequencies, and percentages, are used to summarize demographic and key study variables. The data analysis was done using SPSS version 25.0 and Kolmogorov Smirnov and Shapiro Wilk tests which were used to assess normality, non-parametric tests were used for further analysis.
findingsThe study revealed that while most participants (71.6%) were concerned about the long-term effects of screen use, only 60% were specifically concerned about their own screen time. A significant correlation (r = 0.643, p < 0.01) was found between the frequency and severity of ophthalmic symptoms. Gender and screen illumination showed significant associations with ophthalmic problems, while other demographic factors, including age, education level, and screen usage duration, were not significantly related. Additionally, awareness of the harmful effects of prolonged screen time was significantly associated with attitude (p = 0.05), with males exhibiting a significantly different attitude than females (p = 0.039).
conclusionsand recommendations. The findings highlighted significant associations between gender, screen illumination, and ophthalmic symptoms. Despite awareness of the risks, many participants did not take proactive steps to mitigate the effects of prolonged screen exposure. The study emphasizes the need for educational initiatives and targeted interventions to address screen-related eye effects.
