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

Isolated neutropenia is often deemed benign in elderly patients, frequently attributed to age-related marrow changes, medications, or nutritional deficiencies. However, persistent and unexplained neutropenia may signal early clonal hematopoiesis or evolving myeloid malignancy. While acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) usually arises from multilineage cytopenia, presentation with isolated neutropenia and myeloproliferative neoplasia (MPN)-like features is exceedingly rare. This case underscores the importance of early, risk-adapted assessment in such scenarios. A 69-year-old woman presented with isolated mild neutropenia (absolute neutrophil count (ANC) 1,188/µL) and easy bruising. With no other cytopenias or symptoms, bone marrow biopsy was deferred. Six months later, she developed abdominal discomfort, anorexia, and massive splenomegaly. Laboratory tests revealed leukocytosis with left shift, anemia, thrombocytopenia, and nucleated red cells. Bone marrow biopsy showed > 40% myeloblasts, trilineage dysplasia, and mild fibrosis.
