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.
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
Ephrin type-A receptor 2 (EPHA2) and one of its ligands, ephrin-A5 (EFNA5), have been associated with loss of eye lens transparency, or cataract, - an important cause of visual impairment. Here we show that mice functionally lacking EPHA2 (Epha2-null), EFNA5 (Efna5-null), or both receptor and ligand (Epha2/Efna5-null) consistently develop mostly transparent lenses with an internal refractive disturbance and a grossly disturbed cellular architecture. In situ hybridization localized Epha2 and Efna5 transcripts to lens epithelial cells and nascent fiber cells at the lens equator. In vivo labeling of Epha2-null lenses with a thymidine analog detected a significant decrease in lens epithelial cell proliferation within the germinative zone resulting in impaired early lens growth. Ex vivo imaging of Epha2-null, Efna5-null, and Epha2/Efna5-null lenses labelled in vivo with a membrane-targeted red fluorescent protein revealed misalignment of elongating fiber cells at the lens equator and loss of Y-suture pattern formation near the anterior and posterior poles of the lens. Immuno-fluorescent labeling of lens major intrinsic protein or aquaporin-0 (MIP/AQP0) showed that the precise, radial column patterning of hexagonal fiber cells throughout the cortex region was disrupted in Epha2-null, Efna5-null and Epha2/Efna5-null lenses. Collectively, these data suggest that Epha2 and Efna5 participate in the complex, global patterning of lens fiber cells that is necessary for maximal optical quality.
