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

Rhegmatogenous Retinal Detachment (RRD) is a severe ocular condition characterized by the detachment of the neurosensory retina from the retinal pigment epithelium and caused by retinal tears. Pars Plana Vitrectomy (PPV) is the standard surgical procedure for RRD, and is intended to remove the vitreous gel, which shapes the eye, and provides mechanical and nutritional support to the retina. The study of the vitreous proteome isolated from RRD patients may help decipher the pathobiology of the disease and that of its complications, such as proliferative vitreo-retinopathy (PVR), which predispose to recurrent retinal detachment (observed in 20% of cases), a sight threatening condition. Herein, we set up a pilot shot-gun proteomics study (Data are available via ProteomeXchange with identifier PXD057155) to investigate the perturbations of vitreous proteome comparing RRD patients (n = 8) to patients affected by idiopathic Epiretinal Membranes (ERM), used as controls (n = 8). Spectra were first searched and analyzed to identify proteome perturbations. Thereafter, starting from the hypothesis that RRD could be sustained by altered proteolytic processing of structural and non-structural elements of vitreous gel, N- and C-termini were mined to uncover endogenous proteolytic events. Our search revealed a comprehensive array of proteolytic events and sites across numerous proteins. While some of these were previously documented in different biological samples (like plasma, cell models, etc.), our findings point to new, potentially specific cleavage sites on macromolecular components unique to the vitreous fluid and retinal layers (e.g., interphotoreceptor matrix proteoglycan 1 and 2). Comparison between the N- and C-termini landscapes and the perturbations of global proteome highlighted robust alterations of the repertoire of cleaved proteins between RRD patients and reference control subjects. Additional immunoblotting studies on a selection of proteins envisage that RRD is characterized by unbalanced proteolysis of structural and non-structural components involved in the regulation of immune processes, proteolytic control and, particularly, angiogenesis.
