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

Wet age-related macular degeneration (wAMD), characterized by choroidal neovascularization (CNV), is a leading cause of irreversible vision loss among elderly people in developed nations. Subretinal fibrosis, mediated by epithelial-mesenchymal transition (EMT) of retinal pigment epithelium (RPE) cells, leads to unsuccessful anti-vascular endothelial growth factor (VEGF) agent treatments in CNV patients. Under hypoxic conditions, hypoxia-inducible factor-1α (HIF-1α) increases the stability and activation of p53, which activates microRNA-34a (miRNA-34a) transcription to promote fibrosis. Additionally, Klotho is a target gene of miRNA-34a that inhibits fibrosis. This study aimed to explore the role of the HIF-1α/p53/miRNA-34a/Klotho axis in subretinal fibrosis and CNV. Hypoxia-induced HIF-1α promoted p53 stability, phosphorylation and nuclear translocation in ARPE-19 cells (a human RPE cell line). HIF-1α-dependent p53 activation up-regulated miRNA-34a expression in ARPE-19 cells following hypoxia. Moreover, hypoxia-induced p53-dependent miRNA-34a inhibited the expression of Klotho in ARPE-19 cells. Additionally, the HIF-1α/p53/miRNA-34a/Klotho axis facilitated hypoxia-induced EMT in ARPE-19 cells. In vivo, blockade of the HIF-1α/p53/miRNA-34a/Klotho axis alleviated the formation of mouse laser-induced CNV and subretinal fibrosis. In short, the HIF-1α/p53/miRNA-34a/Klotho axis in RPE cells promoted subretinal fibrosis, thus aggravating the formation of CNV.
