m6A regulators could stratify osteosarcoma patients that were prognostically different. (A) Clustering of osteosarcoma samples from TCGA based on their mRNA expression values of the 12 m6A regulators via K-means method. (B) Kaplan–Meier survival curves of osteosarcoma patients from TCGA stratified by cluster. (C) PCA scatter plot of osteosarcoma samples from TCGA along first 2 principal components. Scatter shapes and colors are used to distinguish samples within different K-means clusters. PCA = principle component analysis, TCGA = the Cancer Genome Atlas.
