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: Bladder amyloidosis is a rare condition characterized by amyloid fibril deposition in the bladder, often mimicking bladder cancer. Diagnosis requires histological analysis of the examination, and treatment typically involves transurethral resection. Case Presentation: An 80-year-old male presented with gross hematuria. Computed tomography suggested bladder cancer with pulmonary metastases. However, due to the extent of the bladder tumor, complete resection was not feasible, and only a limited transurethral resection was performed for diagnostic purposes. Pathological examination revealed bladder amyloid λ amyloidosis. Remarkably, five months post-surgery, both bladder and pulmonary lesions resolved spontaneously. No recurrence was observed during six years of follow-up. Conclusions: This case highlights a rare instance of spontaneous remission in bladder amyloidosis. However, such occurrences were exceedingly uncommon, and systemic amyloidosis can progress to a life-threatening condition. Therefore, careful follow-up, surgical removal, or systemic therapy is essential for bladder amyloidosis.
