Bowel complications requiring surgical intervention in kidney transplant recipients: a retrospective study of clinical characteristics and risk factors.

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
Background: Bowel complications following kidney transplantation (KT) are rare but life-threatening, often necessitating bowel resection. These complications are associated with immunosuppressive therapy, comorbidities, and viral infections. This study aimed to analyze the characteristics and risk factors of patients who underwent bowel resection after KT. Methods: A retrospective review was conducted of 31 KT recipients who underwent bowel resection between 1990 and 2020 at a single center. Patient data, including demographics, comorbidities, transplant-related factors, cytomegalovirus (CMV)/Epstein-Barr virus (EBV) infections, and surgical outcomes, were analyzed. Results: Bowel resection was necessary in under 0.5% of KT recipients, primarily for perforation (48.4%), ischemia, posttransplant lymphoproliferative disorder, and obstruction. Bowel inflammation was the most common cause of perforation, followed by fungal infection (e.g., aspergillosis, mucormycosis) and Kayexalate ileitis. The mean patient age was 53.6±14.2 years, and 54.8% were male. Notable characteristics of those undergoing bowel resection included ABO incompatibility (25.8%), cardiac comorbidities (29.0%), diabetes mellitus (41.9%), and history of retransplantation (19.4%). Bowel resection was performed at an average of 54.3 months post-KT (standard deviation, 77.2 months). All patients were CMV immunoglobulin G (IgG) positive and 91.3% were EBV IgG positive, indicating prior viral infections. Conclusions: Although infrequent, bowel complications represent a serious concern for KT recipients. Identifying contributing factors-including viral infections, comorbidities, and immunosuppressive therapies-could aid in recognizing patients at high risk. Implementing preventive strategies and closely monitoring KT recipients may help reduce the incidence of these complications and improve posttransplant outcomes.
