Alterations of several types of metabolites related to microbiota-gut-brain axis in urine of children with autism spectrum disorder.

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
Introduction: Multiple studies have shown that autism spectrum disorder (ASD) is accompanied by abnormalities in multiple metabolic pathways, however, the fluctuations of certain metabolites involved in these pathways have shown controversial results. This study aimed to identify metabolic characteristics that can distinguish children with ASD by using targeted metabolomics analysis on several types of metabolites related to the microbiota-gut-brain axis. Methods: A total of 54 children with ASD and 47 healthy children (HC) were recruited. Data from the Autism Behavior Checklist (ABC) scale for children with ASD were collected. Based on chromatography/mass spectrometry analysis, the metabolic characteristics of several types of metabolites related to the microbiota-gut-brain axis were discovered in urine samples. Single-variable and multi-variable analyses were conducted using MetaboAnalyst 6.0 and SPSS 27.0.1 to identify potential differential metabolites. The association between differential metabolite concentrations and ABC scores in children with ASD was evaluated using Spearman's rank correlation analysis. Results and Discussion: Seven differential indicators, namely the ratio of cortisol to cortisone (R), creatinine, cortisol, taurine, histamine, homocysteine, and methionine were identified. The combined index diagnostic model constructed based on these indicators demonstrated strong discriminatory power, with an area under the receiver operating characteristic (ROC) curve of 0.943, a sensitivity of 92.6%, and a specificity of 93.7%. The above-mentioned biochemical indicators may be involved in the pathological physiological process of autistic behavioral symptoms from different aspects. These findings contribute to a better understanding of the underlying mechanisms of ASD.
