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

Implanted foreign materials, used to restore or assist tissue function, elicit an initial acute inflammatory response followed by chronic fibrosis that leads to the entrapment of the biomaterial in a thick, poorly vascularized collagenous capsule. Matricellular proteins, secreted macromolecules that interact with extracellular matrix proteins but do not in themselves serve structural roles, have been identified as important mediators of the foreign body response that includes inflammation, angiogenesis, and collagen synthesis and assembly. In this report we delineate functions of hevin and SPARC, two homologs of the SPARC family of matricellular proteins, in the foreign body response. Despite their sequence similarity, hevin and SPARC mediate different aspects of this fibrotic response. Using mice with targeted gene deletions, we show that hevin is central to the progression of biomaterial-induced inflammation whereas SPARC regulates the formation of the collagenous capsule. Although vascular density within the capsule is unaltered in the absence of either protein, SPARC-hevin double-null capsules show substantially increased numbers of vessels, indicating compensatory functions for these two proteins in the inhibition of angiogenesis. These results provide important information for further development of implant technology.
