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

objectiveOur objective was to determine a mechanism for the thrombocytopenia of murine Wiskott-Aldrich syndrome (WAS). MATERIALS AND

methodsConsumption rates of WAS protein (WASP)(-) and wild-type (WT) platelets were measured by injection of 5-chloromethylfluorescein diacetate (CMFDA)-labeled platelets into WT or WASP(-) recipients, and by in vivo biotinylation. Platelet and reticulated platelet counts were performed using quantitative flow cytometry. Bone marrow megakaryocyte number and ploidy was assessed by flow cytometry. Phagocytosis of CMFDA-labeled, opsonized platelets was assessed using bone marrow-derived macrophages. Serum antiplatelet antibodies were assayed via their binding to WT platelets.

resultsCMFDA-labeled WASP(-) platelets are consumed more rapidly than WT platelets in either WT or WASP(-) recipients. In vivo biotinylation studies corroborate these findings and show a normal consumption rate for WASP(-) reticulated platelets. The number of reticulated platelets is reduced in WASP(-) mice, but a significant number of the mice show an increased proportion of reticulated platelets and more severe thrombocytopenia. Sera from some of the latter group contain antiplatelet antibodies. Compared to WT platelets, WASP(-) platelets opsonized with anti-CD61 or 6A6 antibody are taken up more rapidly by bone marrow-derived macrophages. In vivo consumption rates of WASP(-) platelets are more accelerated by opsonization than are those of WT platelets.

conclusionBoth rapid clearance and impaired production contribute to the thrombocytopenia of murine WAS. Increased susceptibility of opsonized WASP(-) platelets to phagocytosis leads to increased in vivo clearance. This correlates with a higher incidence of individuals with an elevated fraction of reticulated platelets, a more severe thrombocytopenia, and antiplatelet antibodies.
