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
Diabetic retinopathy is one of the major complications of diabetes and the main cause to lead to blindness for diabetic patients. However, the exact mechanisms involved in the progression of diabetic retinopathy are not completely known. Herein, we demonstrated a novel role of miR-221-3p in the microvascular dysfunction in diabetic retinopathy. MiR-221-3p expression was found to be substantially upregulated in the retina samples of diabetic rats. Besides, ganglion cell layer, inner nuclear layer, outer nuclear layer, and retinal pigment epithelium layer of diabetic rats expressed higher miR-221-3p than the matched areas of normal rats. High glucose-treated retinal microvascular endothelial cells RF/6A and HRECs exhibited higher miR-221-3p than that in normal condition. MiR-221-3p inhibition could alleviate the retinal vascular leakage induced by diabetes in vivo as evaluated by Evans blue leakage assay, and reduce the proliferation, accelerate the apoptosis development, and inhibit the migration capacity of high glucose-treated RF/6A cells in vitro, while miR-221-3p overexpression partially enhanced the detrimental effects. By bioinformatics analysis and luciferase reporter assay, we identified that TIMP3 is the direct target of miR-221-3p. TIMP3 overexpression counteracted the effect of miR-221-3p on the vessel leakage and endothelial cell function. In conclusion, this study highlights the negative role of miR-221-3p in the microvascular dysfunction in diabetic retinopathy by targeting TIMP3, representing a potential therapeutic target for human diabetic retinopathy.
