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
Purpose: Convergence insufficiency (CI) is a common binocular vision disorder associated with visual discomfort during near tasks, yet occupational differences in convergence-related symptoms remain poorly understood. Therefore, this study aimed to compare convergence-related symptom burden across eight occupational categories using the validated Arabic Convergence Insufficiency Symptom Survey (CISS) and to identify which occupational groups show the greatest symptom burden. Methods: In this cross-sectional survey, adults aged 18 years or older from the Qassim region of Saudi Arabia completed the validated Arabic CISS. Participants represented eight occupational categories. Individuals with high refractive error or dry eye disease were excluded. Symptomatic status was defined as CISS ≥21. Differences in prevalence across occupations were assessed using chi-square tests. Multivariable logistic regression identified predictors after adjustment for age and gender. Results: A total of 751 participants were included (mean age 28.9 ± 9.1 years; 56.3% male). The overall mean CISS score was 16.9 ± 10.7, and 268 participants (35.7%) met the symptomatic threshold. Although unadjusted prevalence did not differ significantly across occupations (χ Conclusion: Convergence-related symptoms are common in working-age adults and show occupational variation after adjustment for demographic factors. Occupations with sustained near visual demands may warrant targeted vision screening and clinical evaluation for convergence insufficiency, supporting the integration of visual health into occupational health policies and preventive healthcare strategies.
