This groundbreaking human study on the ASD microbiome includes probiotic clinical trials, investigation of treatment biomarkers, machine learning/deep learning platform development for ASD classification and prediction, and identification of diagnostic biomarkers. Upon completion, the investigators anticipate publishing at least 12 SCI papers and/or patents and establishing an auxiliary diagnosis platform for both clinical and academic purposes. The findings will offer new insights into the pathogenetic mechanisms, improving early detection, diagnosis, and treatment, ultimately advancing precision medicine for ASD.
