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

Normally factor (F) VIII is not expressed in megakaryocytes, but when human FVIII was transgenically expressed in murine megakaryocytes, it was stored in platelet alpha-granules and released at sites of injury. This platelet FVIII (pFVIII) is effective in correcting hemostasis, even in the presence of circulating inhibitors, so it offers a potential gene therapy strategy for hemophilia A. To understand clot development by pFVIII, we have examined clot response to laser injury in both cremaster arterioles and venules in FVIII(null) mice either infused with FVIII or transgenic for pFVIII. In both sets of vessels, pFVIII is at least as effective as infused FVIII. However, there are temporal and spatial differences in fibrin and platelet accumulation within clots depending on how FVIII is delivered. These differences may be related to the temporal and spatial distribution of the alpha-granular-released FVIII within the developing clot, and may explain the increased frequency and size of embolic events seen with pFVIII. These observations may not only have implications for the use of pFVIII in gene therapy for hemophilia A, but may also have physiologic consequences, explaining why many procoagulant factors are delivered both in the plasma and in platelet alpha-granules.
