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

Collagens are often considered a metazoan hallmark, with the fibril-forming fibrillar collagens present from sponges to human. From evolutionary studies, three fibrillar collagen clades (named A, B, and C) have been defined and shown to be present in mammals, whereas the emergence of the A and B clades predates the protostome/deuterostome split. Moreover, several C clade fibrillar collagen chains are present in some invertebrate deuterostome genomes but not in protostomes whose genomes have been sequenced. The newly sequenced genomes of the choanoflagellate Monosiga brevicollis, the demosponge Amphimedon queenslandica, and the cnidarians Hydra magnipapillata (Hydra) and Nematostella vectensis (sea anemone) allow us to have a better understanding of the origin and evolution of fibrillar collagens. Analysis of these genomes suggests that an ancestral fibrillar collagen gene arose at the dawn of the Metazoa, before the divergence of sponge and eumetazoan lineages. The duplication events leading to the formation of the three fibrillar collagen clades (A, B, and C) occurred before the eumetazoan radiation. Interestingly, only the B clade fibrillar collagens preserved their characteristic modular structure from sponge to human. This observation is compatible with the suggested primordial function of type V/XI fibrillar collagens in the initiation of the formation of the collagen fibrils.
