Risk factors of preoperative bowel dysfunction in acute Stanford B aortic dissection.
Article in American journal of translational research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the risk factors for preoperative bowel dysfunction in patients with acute Stanford Type B aortic dissection.
methodsA retrospective analysis was conducted on 184 patients diagnosed with Stanford Type B aortic dissection between January 2023 and December 2024. These patients were divided into two groups: the bowel dysfunction group (n = 49) and the non-bowel dysfunction group (n = 135). Baseline characteristics, echocardiographic findings, myocardial enzyme levels, dietary habits, and psychological status were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors. A nomogram was developed to facilitate clinical prediction.
resultsPreoperative constipation was observed in 26.63% (49/184) of patients. Logistic regression analysis identified older age, higher Self-Rating Depression Scale (SDS) score and Self-Rating Anxiety Scale (SAS) score as independent risk factors for preoperative bowel dysfunction. Conversely, higher intake of fruits, vegetables, and water was associated with a reduced risk. The nomogram demonstrated good predictive performance, with an AUC of 0.930 in the training cohort and 0.884 in the validation cohort.
conclusionsPreoperative bowel dysfunction is common among patients with acute Stanford Type B aortic dissection. Age, dietary habits, and psychological status are significant risk factors. Close monitoring and targeted management of these factors may help reduce the incidence of preoperative bowel dysfunction.
