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

backgroundRenal carcinoma is the third most common urological cancer, with 30% of patients presenting with metastases at diagnosis. Metastases to the small intestine are rare (0.7-1.1%), and their presentation as intestinal intussusception is even more uncommon, with only a few cases reported in the literature.

aimsThe aim of the study was to present a case of stage IV clear cell renal carcinoma with a rare presentation of intestinal intussusception, leading to emergency department admission due to severe anemia and melena.

methodsA 62-year-old man presented with melena for 2 months and a critically low hemoglobin level of 2.9 g/dL (normal range: 13.5-17.5 g/dL). Abdominal and pelvic angiotomography identified an exophytic lesion in the left kidney consistent with renal carcinoma and an approximately 16 cm ileal intussusception.

resultsExploratory laparotomy revealed intestinal intussusception and a 4 cm lesion on the antimesenteric border, suspected to be a tumor. A segmental resection with primary anastomosis was performed, resulting in a favorable postoperative recovery. Histopathological and immunohistochemical analyses confirmed poorly differentiated metastatic clear cell renal carcinoma.

conclusionsThis report underscores the need to consider gastrointestinal symptoms in patients with renal carcinoma, as an intestinal metastasis, although rare, is a potential complication. Synchronous metastases are even rarer and present a significant diagnostic challenge.
