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 nationwide survey was conducted for identifying ataxia-telangiectasia (AT) patients in Japan. Eighty-nine patients were diagnosed between 1971 and 2006. Detailed clinical and laboratory data of 64 patients including affected siblings were collected. Analyses focused on malignancy, therapy-related toxicity, infection, and hematological/immunological parameters. The phenotypic variability of AT was assessed by comparing 26 affected siblings from 13 families. Malignancy developed in 22% of the cases and was associated with a high rate of severe therapy-related complications: chemotherapy-related cardiac toxicity in 2 children, and severe hemorrhagic cystitis requiring surgery in 2 patients. The frequency of serious viral infections correlated with the T cell count. Hypogammaglobulinemia with hyper-IgM (HIGM) was recorded in 5 patients, and 3 patients developed panhypogammaglobulinemia. Differences in immunological parameters were noted in siblings. Four patients showed an HIGM phenotype, in contrast to their siblings with normal IgG and IgM levels. The patients with HIGM phenotype showed reduced levels of TRECs and CD27+CD20+ memory B cells. The findings suggest that hitherto unidentified modifier genes or exogenous environmental factors can influence the overall immune responses. Our data along with future prospective study will lead to better understanding of the hematological/immunological phenotypes and to better care of the patients.
