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

backgroundAge-related macular degeneration (AMD) is a multifactorial retinal disease in which alterations in lipid metabolism and dysregulation of the complement system play a central role. The aim of this study was to characterize a novel double-knockout (DK) mouse model deficient in apolipoprotein E and complement factor H (ApoE

methodsApoE

resultsDK mice exhibited significant RPE thinning, disruption of tight junctions, vacuolization, and BM thickening (p < 0.05). Lipid accumulation and plasma lipid levels significantly increased compared with controls (p < 0.01). Complement activation was significantly enhanced, as evidenced by increased C5b-9 deposition (p < 0.01). In addition, DK mice exhibited increased vascular endothelial growth factor expression (p < 0.05), altered matrix metalloproteinase activity (p < 0.05), and significant synaptic disorganization between photoreceptors and second-order neurons (p < 0.05).
