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
BackgroundTo investigate the underlying mechanism of S100A4 function and whether it has a role in retinal neovascularization (RNV) in a mouse model of oxygen-induced retinopathy (OIR).MethodsRetinas from a mouse model of OIR were treated with and without an intravitreous injection of adenoviral-S100A4-RNAi or adenoviral green fluorescence protein (GFP) at postnatal day 12 (P12). At P17, the efficacy of adenoviral gene transfer was assessed using fluorescence microscopy and western blot analysis. RNV was evaluated by whole-mount immunofluorescence staining of the mouse retina and by counting the number of pre-retinal neovascular cells. Protein and mRNA expression levels of S100A4, brain-derived growth factor (BDNF), and vascular endothelial growth factor (VEGF) were measured using western blot analysis and real-time PCR.ResultsRetinal S100A4 levels were positively correlated with the progression of RNV. In the OIR-S100A4-RNAi group, both protein and mRNA expression levels of S100A4 in the retina significantly decreased at P17 compared with those in the OIR group. Ad-S100A4-RNAi transfer was clearly demonstrated by GFP fluorescence in many layers of the retina 5 days after the Ad-S100A4-RNAi transfer. Whole-mount immunofluorescence staining of the retina and quantification of the pre-retinal neovascular cells demonstrated that RNV was significantly inhibited. Meanwhile, the levels of the transcription and translation of BDNF, VEGF, and hypoxia-inducible factor-1α (HIF-1α) significantly decreased in the OIR-S100A4-RNAi group.ConclusionsAd-S100A4-RNAi transfer ameliorates RNV. The related mechanism may involve silencing S100A4 to decrease the activation of BDNF, which downregulates VEGF expression via HIF-1α. This finding could provide a new therapeutic target for the treatment of ocular neovascularization diseases.
