Correlation analysis of serum miRNA expression levels with the degree of macular edema in patients with retinal vein occlusion and its clinical implications.

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
Objective: To investigate the correlation between serum microRNA (miRNA) levels and the degree of macular edema in retinal vein occlusion (RVO) patients. Methods: 180 RVO patients were divided into three groups based on macular edema severity: mild, moderate, and severe. Their serum miR-155-5p, miR-17-5p, and miR-375 levels were compared with 60 healthy controls. Pearson correlation analysis assessed the relationship between miRNA levels and clinical outcomes. Results: miR-155-5p levels were significantly higher in RVO groups compared to controls, while miR-17-5p and miR-375 levels were lower. Increased severity of macular edema correlated with higher miR-155-5p and lower miR-17-5p and miR-375 levels. After treatment, miR-155-5p levels decreased, while miR-17-5p, miR-375, and visual acuity improved. Correlation analysis showed that changes in miR-155-5p were negatively correlated with visual improvement and macular edema resolution, while miR-17-5p and miR-375 were positively correlated with these outcomes. Conclusion: Serum miR-155-5p, miR-17-5p, and miR-375 levels are associated with macular edema severity in RVO. These miRNAs may serve as biomarkers for disease progression and prognosis, aiding personalized treatment strategies.
