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

purposeTo investigate the expression patterns of Fibrillin-1 in idiopathic epiretinal membranes (iERM) and identify Fibrillin-1-secreting cells.

methodsiERM samples were collected via standard 27-gauge vitrectomy and subsequently subjected to flat-mount immunohistochemistry with double staining for the following markers: Fibrillin-1, glial acidic fibrillary protein (GFAP), cellular retinaldehyde-binding protein (CRALBP), retinoid isomerohydrolase RPE65 (RPE65), and α-smooth muscle actin (α-SMA).

resultsFibrillin-1 was detected throughout the iERM. The colocalization of Fibrillin-1 with α-SMA, CRALBP, and RPE65 suggested that myofibroblasts and retinal pigment epithelial (RPE) cells secreted Fibrillin-1. The lack of colocalization between GFAP and Fibrillin-1 indicated that GFAP-positive glial cells did not secrete Fibrillin-1. The colocalization of CRALBP and RPE65 with α-SMA indicated the transformation of RPE cells into myofibroblasts. This suggested that RPE cells transformed into myofibroblasts and secreted Fibrillin-1. The lack of colocalization between GFAP and α-SMA implied that GFAP-positive glial cells did not express α-SMA.

conclusionsFibrillin-1 is widely distributed in iERMs, and myofibroblasts were the primary sources of Fibrillin-1 secretion. Additionally, during their transformation into myofibroblasts, RPE cells secreted Fibrillin-1. GFAP-positive glial cells did not express α-SMA nor secrete Fibrillin-1. KEY MESSAGES: What is known Idiopathic epiretinal membranes are a common cause of visual acuity and quality impairment. The protein and cell components of idiopathic epiretinal membrane exhibit diversity. What is new Fibrillin-1 is present throughout the idiopathic epiretinal membrane. Myofibroblasts are the most important source of Fibrillin-1 secretion. Retinal pigment epithelial cells also secrete Fibrillin-1 when transforming into myofibroblast. Glial cells do not transform to myofibroblast and do not secrete Fibrillin-1.
