Metachronous multiple primary cancers involving pulmonary non-Hodgkin lymphoma and bladder cancer: a case report.
Article in Frontiers in oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Multiple primary cancers (MPC) are characterized by the synchronous or metachronous occurrence of two or more distinct histopathological tumor types. We report a rare clinical case of a 65-year-old woman diagnosed with pulmonary mucosa-associated lymphoid tissue (MALT) marginal zone B-cell lymphoma and subsequent invasive bladder carcinoma. The patient, previously treated with multiple lines of chemotherapy for MALT lymphoma, was admitted to our hospital with lower abdominal and perineal pain accompanied by gross hematuria for one week. Cystoscopic examination and transurethral resection of the bladder lesion confirmed the diagnosis of bladder cancer. She later underwent laparoscopic radical cystectomy, and postoperative histopathological evaluation revealed invasive urothelial carcinoma infiltrating the cervical and vaginal fornix stroma.
