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

backgroundDiamine oxidase (DAO) is secreted by epithelial cells in the intestinal villi, and its serum levels are elevated after intestinal mucosal damage. d-lactate (D-LA) is a gut microbial metabolite that can enter the systemic circulation if intestinal barrier function is impaired. Both DAO and D-LA are serum markers of small bowel mucosal integrity, and can be valuable biomarkers of intestinal barrier damage in inflammatory bowel disease (IBD). Intestinal barrier dysfunction was recently found to contribute to psychological symptoms in IBD patients. However, the correlations among DAO, D-LA, psychological symptoms, and disease activity in IBD remain unexplored.

aimTo explore the correlations between serum markers of intestinal barrier dysfunction and psychological symptoms in IBD.

methodsWe enrolled of 126 participants in this study. Psychological symptom questionnaires (depression, patient health questionnaire-9; anxiety, generalized anxiety disorder-7; and stress, perceived stress scale) and a quality of life (QOL) questionnaire (IBD questionnaire 32) were collected at the baseline. Serum DAO and D-LA levels were measured to assess intestinal barrier integrity. Receiver operating characteristic (ROC) curves were used to identify candidate markers of psychological symptoms and disease activity in IBD patients. Logistic regression was applied, with DAO as an independent variable for predicting psychological symptoms in IBD.

resultsSerum DAO levels were significantly higher in IBD patients with moderate-to-severe psychological symptoms than in patients with mild or no psychological symptoms. DAO was positively correlated with depression and negatively correlated with QOL in IBD patients. ROC curves revealed that DAO was independently associated with psychological symptoms and clinical activity in patients with IBD. Additionally, logistic regression analysis revealed that each 1-ng/mL increase in DAO levels was significantly associated with an increased risk of psychological symptoms in IBD patients (OR: 1.019, 95%CI: 1.002-1.037). These results highlight the potential of DAO as a novel biomarker for both depression and disease activity in IBD patients.

conclusionThis study indicates that DAO may be associated with depression and disease activity in IBD patients; however, prospective studies are required to validate its causal relationship.
