FIGURE 3. Comparison of the relative abundance of microbial taxa between the two specimen collection types for ESCC and GCA.
(A) Mean relative abundance of the top ten prevalent genera in swab and biopsy specimens of ESCC. (B) Mean relative abundance of the top ten prevalent genera in swab and biopsy specimens of GCA. Statistical differences were calculated between two specimen types using the Wilcoxon signed-rank test, and error bars are the standard error of the mean. An unclassified genus similar to Prevotella is indicated as [Prevotella]. An unclassified bacterium at the genus level was shown as f_Enterobacteriaceae;.
