Consensus clustering for tumor-infiltrating immune cells. (A) Two ICI clusters were generated from unsupervised clustering of the ICI profile data of the training cohort. Rows represent ICI types, and columns represent OS samples. (B) Overall survival-based Kaplan–Meier estimator of two ICI clusters in the training cohort. The log-rank test showed an overall p = 0.046. ICI, immune cell infiltration; OS, osteosarcoma.
