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

T-cell large granular lymphocytic leukemia (T-LGLL) is an uncommon lymphoproliferative disorder that typically follows a slow clinical course. Symptoms often remain subtle until cytopenia or infection develops. Severe infection secondary to neutropenia represents the major cause of mortality. We describe an uncommon case involving an 81-year-old woman diagnosed with T-LGLL whose agranulocytosis was followed by recurrent infections. Immunosuppressive agents such as methotrexate, cyclophosphamide, and tacrolimus-commonly recommended by current guidelines-were administered but failed to improve neutropenia. Administration of fludarabine, a purine analog listed as a second-line option in the NCCN guidelines, led to a prompt rise in neutrophil counts and a concomitant decline in LGL levels. To our knowledge, no prior Japanese report has documented successful use of fludarabine monotherapy for T-LGLL-related neutropenia, prompting us to describe this case.
