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

Retinal fibrosis is a blinding complication of proliferative diabetic retinopathy (PDR), proliferative vitreoretinopathy (PVR), age-related macular degeneration (AMD) and idiopathic epiretinal membrane (iERM), yet effective therapies remain lacking. The purpose of this study was to investigate the role of BMP2 and BMP4 (BMP2/4)-activin receptor-like kinase (ALK) signaling in retinal fibrosis. BMP2 was detected in the vitreous of PDR, PVR, and rhegmatogenous retinal detachment (RRD) samples at concentration of 70, 180, and 85 pg/mL respectively, whereas it was present only at trace levels or was undetectable in the vitreous of macular hole and idiopathic ERM samples (~0.1 pg/mL). PDR, PVR, and idiopathic ERMs exhibited strong immunoreactivity for BMP2, BMP4, ALK3 (Bmpr1a), pSMAD1/5/9, and pSMAD4. Formation of preretinal fibronectin-containing membranes resulted from intravitreal injection of wild-type mice with BMP2 and similar membranes formed in mice expressing constitutively active ALK3 (caBmpr1a). The presence of preretinal membrane in
