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

A family with four and an unrelated family with three individuals affected by the May-Hegglin anomaly are described. Platelet counts were markedly reduced and were correctly determined only in the counting chamber. Bleeding time and platelet aggregation were always normal, but platelet nucleotide concentrations (ATP and ADP) were elevated. The platelet glycoprotein complexes Ib/IX, IIb/IIIa and Ia/IIa were quantitatively normal. Platelet-associated IgG was slightly elevated, although thrombocytopenia was presumably not caused by an immunological mechanism. Morphological investigations showed giant platelets and spindle-shaped inclusion bodies in the granulocytes, while their function (phagocytic capacity, radical production) was normal. To exclude hereditary types of thrombocytopenia, morphological and family investigations are required to avoid misdiagnosis with far-reaching diagnostic and therapeutic consequences.
