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: Combination therapy with immune checkpoint inhibitors (ICIs) has become a standard treatment for metastatic renal cell carcinoma (mRCC). However, ICIs may also cause immune-related adverse events. We report a case of mRCC that developed fulminant immune-related enterocolitis. Case Presentation: A 79-year-old man received ICIs therapy for mRCC and was urgently hospitalized because of worsening diarrhea. Despite the initiation of steroid therapy, circumferential intestinal necrosis developed, necessitating subtotal colectomy. The patient subsequently developed cytomegalovirus- and Epstein-Barr virus-associated enterocolitis and died from extensive intestinal necrosis caused by severe thrombosis secondary to disseminated intravascular coagulation. Conclusion: Persistent diarrhea during ICIs therapy requires prompt evaluation and specialist consultation, even when symptoms appear mild, as they may signal immune-related enterocolitis. Clinicians should also remain vigilant for infectious complications, which can exacerbate the severity of immune-related enterocolitis and lead to life-threatening outcomes.
