Identification of ICD-associated subtypes by consensus clustering. (A) Construction of interactive functions between ICD-related genes; (B) Identification of two ICD-related subtypes by consensus clustering; (C, D) The delta area curve of consensus clusters represents the relative change of the area under the cumulative distribution function (CDF) curve from k = 2 to 10; (E) Heatmap of the expression of ICD-related genes in different subtypes. Red represents high expression; blue represents low expression; (F) Kaplan-Meier curves for different ICD subtypes
