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

purposeImmunodeficiency, centromeric instability, and facial anomalies (ICF) syndrome is an extremely rare autosomal recessive disease. The immune phenotype is characterized by hypogammaglobulinemia in the presence of B cells. T cell lymphopenia also develops in some patients. We sought to further investigate the immune defect in an ICF patient with a novel missense mutation in DNMT3B and a severe phenotype.

methodsPatient lymphocytes were examined for subset counts, immunoglobulin levels, T and B cell de novo production (via excision circles) and receptor repertoire diversity. Mutated DNMT3B protein structure was modeled to assess the effect of a mutation located outside of the catalytic region on protein function.

resultsA novel homozygous missense mutation, Ala585Thr, was found in DNMT3B. The patient had decreased B cell counts with hypogammaglobulinemia, and normal T cell counts. CD4

conclusionsOur results highlight the existence of a T cell defect that develops over time in ICF patient, in addition to the known B cell dysfunction. With intravenous immunoglobulin (IVIG) treatment ameliorating the B cell defect, the extent of CD4
