The ordinate indicates the number of samples, and the abscissa indicates the ratio of the reads obtained by the corresponding analysis to the total reads before the analysis. b Heat map of miRNA expression characteristics. Yellow represents low expression, and red represents high expression. The abscissa in the heat map shows the sample name, and the ordinate shows the miRNA name. c-e Patients were grouped according to their FR, EER and HQER
