Methotrexate-Associated Lymphoproliferative Disorders Characterized by a T-Cell Phenotype With Lung and Psoas Involvement: A Case Report.
Article in Case reports in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Methotrexate (MTX) can cause MTX-associated lymphoproliferative disorders (MTX-LPDs) characterized by a T-cell phenotype. Herein, we report an extremely rare case of MTX-LPD with peripheral T-cell lymphoma (PTCL) phenotype and lung and skeletal muscle involvement. A 66-year-old man who had received MTX for 8 years for rheumatoid arthritis was admitted for right groin pain. A computed tomography scan revealed masses in the right middle lobe and right psoas muscle and multiple nodules in both lung fields. Pathological and immunohistochemical examinations of a lung nodule and psoas muscle tumor revealed PTCL. Remission was achieved soon after discontinuing MTX.
