1 · What the graph read from it

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.

2 · The registry

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

objectivesThe function of netrin-1 in pathological angiogenesis and its role in retinal neovascularization were investigated in the retinas of oxygen-induced retinopathy (OIR) mice by inhibition of netrin-1.

methodsExpression of netrin-1 mRNA and protein in the retinas of OIR mice was analyzed by quantitative RT-PCR and immunoblotting. Inhibition of retinal neovascularization was achieved by lentivirus-mediated netrin-1 small hairpin RNA (shRNA) infection. Retinal neovascularization was examined by fluorescein angiography and quantification of preretinal neovascular nuclei in retinal sections.

resultsBoth mRNA and protein expression of netrin-1 were significantly upregulated in postnatal day 17 OIR mouse retinas. Treatment of OIR mice with specific lentivirus-mediated netrin-1 shRNA dramatically reduced neovascular outgrowth into the inner limiting membrane. Neovascular tufts and nonperfused areas were also reduced.

conclusionsHigh expression of netrin-1 was detected in the retina under ischemic conditions and played a significant role in pathological retinal angiogenesis. Therefore, netrin-1 represents a potential therapeutic target for diabetic retinopathy, retinopathy of prematurity and other ocular neovascular diseases.
