Association between immune subtypes and sarcoma-related tumor biomarkers. A, B MDM2, CDK4, CD34, and TLE1 expression in sarcoma immune subtypes in TCGA (A) and GSE21050 (B) cohorts. The solid black line in the box represents the median, and the black box in the violin plot represents the quartile range. The dots show the distribution of each sample, and the black vertical line running through the violin chart represents the interval from the minimum value to the maximum value. The Kruskal–Wallis test and Wilcox test were used to assess significant differences among the three groups and pairwise comparisons between groups, respectively. ns, not significant, *P < 0.01, **P < 0.001, ***P < 0.0001, and ****P < 0.00001
