[T-cell large granular lymphocytic leukemia and Felty's syndrome in rheumatoid arthritis].
Article in Zeitschrift fur Rheumatologie, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Neutropenia in rheumatoid arthritis (RA) is a problem that often needs to be addressed. Side effects of basic antirheumatic treatment, infections or substrate deficiencies are common causes; however, T‑cell large granular lymphocytic (T-LGL) leukemia, a mature T‑cell neoplasm, can also lead to autoimmune cytopenia. The T‑LGL leukemia can be associated not only with RA but also with other autoimmune diseases or neoplasms. Correspondingly, increases in clonal T cells, natural killer T (NKT) cells and LGL cells are found in the peripheral blood. A T‑cell receptor PCR and flow cytometry (or at least a blood smear) are therefore necessary to diagnose T‑LGL leukemia. The presence of clonal T cells alone is usually not pathological. A distinction must be made from Felty's syndrome (consisting of the clinical triad of arthritis, leukopenia, splenomegaly), which does not require the two T‑LGL leukemia criteria mentioned. The treatment for both entities (with underlying RA) is methotrexate and, if insufficiently effective, rituximab.
