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

Pathological neovascularization and vascular leakage are central drivers of many sight-threatening diseases. While strategies targeting vascular endothelial growth factor (VEGF) have improved clinical outcomes, many patients do not benefit from the treatment, highlighting the need for alternative therapeutic strategies. Two independent vitreous proteomics studies in patients with proliferative diabetic retinopathy (PDR) reveal a significant reduction in Frizzled-related Protein (FRZB), a finding recapitulated in preclinical models of ocular angiogenesis. Here, we show that loss of Frzb exacerbates ocular angiogenesis, whereas therapeutic delivery of Fc-recombinant FRZB or its netrin-related motif (NTR) robustly suppresses and reverses ocular angiogenesis across various preclinical models. Fc-NTR acts additively with Aflibercept, supporting its potential as a combination therapy. Mechanistically, FRZB binds Caveolin-1 (CAV1), inhibits its phosphorylation at Tyr42, promotes retention of the TGFβ receptor ALK5, and enhances Smad2/3 signalling. These findings define FRZB as a potent suppressor of ocular angiogenesis and establish a promising therapeutic avenue.
