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

Introduction: Secondary malignancies arising in intestinal segments used for urinary diversion are rare, and reports of malignant lymphoma are extremely limited. We report a rare case of follicular lymphoma arising in an ileal neobladder 20 years after radical cystectomy. Case Presentation: An 81-year-old man had undergone radical cystectomy with ileal neobladder reconstruction for muscle-invasive bladder cancer (pT2bN0M0) 20 years earlier and had remained recurrence-free. Follow-up imaging incidentally revealed a large pelvic mass contiguous with the neobladder and multiple enlarged lymph nodes. Transurethral resection led to a diagnosis of follicular lymphoma. Treatment with bendamustine plus rituximab achieved marked tumor reduction without severe adverse events. Conclusion: Malignant lymphoma arising in urinary diversion organs is extremely rare. This case highlights the potential for late-onset lymphoid malignancies following urinary diversion and emphasizes the need for long-term clinical awareness of secondary malignancies in such patients.
