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

Defects of memory B cells and of somatic hypermutation (SHM) are involved in the pathogenesis of common variable immunodeficiency (CVID). Here we report for the first time a systematic study of the relationship between memory B cell deficiency and SHM abnormalities in CVID, and relate these variables to prediagnostic infections. Isotype switched Vh3-23 transcripts were undetectable or low in 30% (IgG) and 63% (IgA) of the patients, but never in controls (P < 0.001). When measurable, the SHM fraction of transcripts was significantly lower in patients (IgM: median 32% vs. 56% (P = 0.0002); IgG: 72% vs. 87% (P = 0.0002); IgA: 81% vs. 88% (P = 0.04)). The concentration of switched (CD19+/CD27+/IgG+) and unswitched (CD19+/CD27+/IgM+/IgD+) memory cells was reduced in 75% and 58% of the patients, respectively. Patients with reduced concentrations of switched memory B cells had normal or low SHM, and only the IgG SHM fraction correlated with prediagnostic incidence of severe respiratory tract infections (P = 0.004).
