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

Collagen V is a regulatory fibril-forming collagen that forms heterotypic fibrils with collagen I. Deletion of collagen V in the mouse is associated with a lack of fibril assembly in the embryonic mesenchyme, with a resultant lethal phenotype. The current work elucidates the regulatory roles of collagen V during development and growth of tissues. A conditional mouse model with a mutation in Col5a1 was developed using a Cre-loxP approach. Col5a1 was ablated in Col5a1(flox/flox) mice using a cornea stroma-specific Kera-Cre driver mouse to produce a bitransgenic Col5a1(Δst/Δst) line that is null for collagen V. This permits analyses of the corneal stroma, a widely used model for studies of collagen V. The collagen-V-knockout stroma demonstrated severe dysfunctional regulation of fibrillogenesis. Fibril diameters were significantly increased, with an abnormal, heterogeneous distribution; fibril structure was abnormal, fibril number was decreased and lamellae were disorganized with decreased stroma thickness. The phenotype was more severe in the anterior versus posterior stroma. Opacity was demonstrated throughout the Col5a1(Δst/Δst) stroma, with significantly increased haze intensity compared with control mice. These data indicate central regulatory roles for collagen V in fibril and matrix assembly during tissue development, with dysfunctional regulation resulting in a functional loss of transparency.
