Flow diagram of the trial; forty-six patients with RAS were enrolled into our trial, and then 11 patients (10 in AA and 1 in AC) were excluded due to data missing from the clinical test analysis. Moreover, 11 patients (7 in AA and 4 in AC) were excluded from high-throughput sequencing analysis as the DNA extraction failed. Additionally, 10 healthy individuals were selected for high-throughput sequencing as a negative control group.
