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

Inflammatory myofibroblastic tumors (IMT) are exceedingly rare, particularly when originating in the bladder. Complete surgical resection is the gold standard treatment for IMTs. We describe a case of IMT of the urinary bladder that achieved complete radiographic and endoscopic resolution after systemic treatment with ipilimumab and nivolumab directed towards metastatic melanoma. This case is noteworthy due to the tumor's serendipitous and remarkable response to immunotherapy.
