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

objectiveUse of high-dose cyclophosphamide without hematopoietic stem cell transplant to treat severe aplastic anemia (SAA) has been controversial due to concern for increased infectious toxicity as compared with antithymocyte globulin and cyclosporine A. As children often tolerate dose-intensive therapy better than adults, we sought to perform a detailed retrospective analysis of both treatment response and toxicity in 28 patients younger than 22 years of age treated with 29 courses of high-dose cyclophosphamide as the sole form of immunosuppression. STUDY

designChildren and adolescents with SAA who lacked an human leukocyte antigen-matched sibling donor were treated with cyclophosphamide 50 mg/kg/d for 4 consecutive days then received daily granulocyte colony stimulating factor until neutrophil recovery, transfusion support, and antimicrobial prophylaxis.

resultsOverall survival was 85%, with hematologic response of 79% and complete response of 66%. Cumulative incidences of bacterial infection (86%) and fungal infection (62%) were high but deaths due to infection were rare, as were clonal evolution (1/28), clinically relevant paroxysmal nocturnal (1/28), and relapse (2/28).

conclusionsResponse rates and survival following high-dose cyclophosphamide in pediatric patients with SAA exceed those seen in adults and compare favorably to antithymocyte globulin/cyclosporine A with manageable infectious toxicity.
