Correlation analysis between SLC26A8, ANKRD22, FCGR1B, and infiltrated immune cells. D. The cluster number is most stable when the k value is set to 2. E. PCA showed significant differences between the two clusters. F. SLC26A8, ANKRD22, and FCGR1B expression in C1 and C2 cases in total cohort. G. Difference of immune cell infiltration between C1 and C2. H. The difference in biological function between C1 and C2 was analyzed by the GSVA method.
