Epstein-Barr virus-associated B-cell type non-Hodgkin's lymphoma with concurrent p53 protein expression in a rheumatoid arthritis patient treated with methotrexate.
Article in International journal of hematology, 2002. 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
A Japanese male patient received various medications for his long-standing rheumatoid arthritis (stage IV, class II). He developed a mass on the right anterior chest wall after being treated with methotrexate (MTX) for 4 months. A biopsy of the mass showed it to be Epstein Barr virus (EBV)-associated lymphoma of B-cell phenotype stage IE (bulky mass), with positive EBV-encoded small RNAs (EBERs) in situ hybridization, EBV latent membrane protein-1 (LMP-1) negative, EB nuclear antigen-2 (ERNA-2) negative, CD20/L26 (+), CD45RO/UCHL-1 (-). A single band of the joined termini of the EBV genome was demonstrated in DNA extracted from the mass, suggesting a clonal disorder of the mass. Immunostaining of the mass with p53 antibody was also positive. With discontinuation of MTX and administration of chemotherapy, the tumor disappeared but recurred after 3 months. This case suggests that concordant p53 expression and latent EBV infection may play an important role in the pathogenesis of lymphomas arising in patients with rheumatoid arthritis who are immunosuppressed with MTX.
