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

Despite our increasing characterization of the molecular basis for many primary immunodeficiency states, significant heterogeneity in clinical and immunological phenotype exists. Epigenetic alterations have been implicated in the pathogenesis of immune dysregulation and may provide a unique paradigm to help us understand the phenotypic heterogeneity in primary immunodeficiency. The occurrence of X-linked thrombocytopenia (XLT) and Wiskott-Aldrich syndrome (WAS) in monozygotic twins is a rare occurrence which allows for the exploration of epigenetic alterations and associated phenotypic heterogeneity. We describe a pair of monozygotic twin brothers with a missense mutation in the WAS gene consistent with reduced expression of the WAS protein, a XLT phenotype, and a good prognosis. Despite this genotype and anticipated mild phenotype in both twins, a discordant phenotype has evolved in which one twin demonstrates asymptomatic thrombocytopenia and the other symptomatic thrombocytopenia, infectious complications, and autoimmunity. Characterization of the potential epigenetic contribution to the spectrum of XLT and WAS is described and the implications of these findings are discussed.
