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: Chemokine receptor 4 (CXCR4) plays an essential role in the early stage of corneal neovascularization (CNV), but the underlying key molecular mechanism has yet to be addressed. This study aimed to explore the new molecular mechanism of CXCR4 in CNV and the related pathological events. Methods: CXCR4 was assayed by immunofluorescence or Western blotting. The function of the supernatant from hypoxia-treated human corneal epithelial cells (HCE-T) cells was examined by culturing with human umbilical vein endothelial cells. MicroRNA sequencing was used to detect the downstream microRNAs upon CXCR4 knockdown and analyzed by preliminary bioinformatics. The proangiogenic functions and downstream target genes of microRNA were investigated by gene interference and luciferase assay. An alkali-burned murine model was introduced to examine the function and mechanism of miR-1910-5p in vivo. Results: High CXCR4 expression was confirmed in corneal tissues of patients with CNV and hypoxic HCE-T cells. The supernatant from hypoxia-treated HCE-T cells is involved in the CXCR4-mediated angiogenesis of human umbilical vein endothelial cells. Notably, miR-1910-5p was demonstrated to be at a high level in wild-type HCE-T cells and its supernatant, and in CNV patient tears. The proangiogenic functions of miR-1910-5p were demonstrated with the assays of cell migration, tube formation, and aortic ring. Moreover, miR-1910-5p significantly inhibited multimerin-2 expression by targeting its 3' untranslated region and caused significant extracellular junctional defects in human umbilical vein endothelial cells. MiR-1910-5p antagomir could significantly increase multimerin-2 level and decrease vascular leakage, and ultimately inhibit CNV in a murine model. Conclusions: Our results revealed a novel CXCR4-mediated mechanism and proved that targeting the miR-1910-5p/multimerin-2 pathway could be a promising therapeutic target for CNV.
