Polyarteritis nodosa: a case report of isolated large bowel involvement and surgical intervention.

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.
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
Polyarteritis nodosa (PAN) is a necrotizing vasculitis commonly affecting small-sized vessels and medium-sized vessels. We present the case of surgical resection for ischemic colitis secondary to PAN. A 26-year-old woman presented with left lower quadrant pain, diarrhea and bloody stools. Colonoscopy showed diffuse circumferential ulceration and necrotic lining from the sigmoid colon to the splenic flexure. A subsequent computed tomography angiography (CTA) revealed left colonic wall thickening, hypoenhancement and multiple inferior mesenteric artery aneurysms, concerning for vasculitis. Ensuing laboratory workup all returned negative. Worsening pain, left-sided peritonitis, tachycardia and rising white blood cell necessitated a colectomy from the proximal descending to upper rectum with an end colostomy. Surgical pathology showed features consistent with PAN. The patient improved significantly after surgery and was discharged on a steroid taper and later started on mycophenolate mofetil. This case is a unique presentation of isolated large intestinal involvement and was treated with both medical and surgical interventions.
