Factors influencing image quality in Tibetan children by optical coherence tomography.

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: This study aim to investigate the clinical findings of subjects characteristics and image quality related factors in Tibetan children by optical coherence tomography (OCT) in epidemiological cohort study. Methods: Participants were 1,856 first-grade students (mean age = 6.82 ± 0.46 years) from seven selected elementary schools in Lhasa. Following comprehensive systemic and ophthalmic examinations, OCT scans were assessed by specialists with manual segmentation as needed. Results: A total of 1,698 students completed the examination protocol in this study (91.5%). After manual screening, 1,447 (78%) and 1,289 (70%) images could be analyzed in the macular and optic disc regions, respectively. Common image flaws were blinking or fixation error (70%+), poor focusing, and positioning errors. Among students who have completed OCT, a higher percentage of boys ( Conclusion: This study underscores the imperative for stringent image quality control in pediatric OCT assessments to ensure precise clinical outcomes.
