The expressions of six snoRNAs and risk score in ccRCC patients’ tissues and serums. A, The comparisons of six‐snoRNA risk score for ccRCC tissues and serums, respectively. The expressions of six snoRNAs in tissues (B‐G) and serums (H‐M). P values were measured by unpaired t test. N, ROC analysis of the sensitivity and specificity of the overall survival prediction by the six‐snoRNA risk score in tissues and serums. O, 3‐D PCA plot analysis of the six‐snoRNA expression data in tissues and serums samples. Abbreviations; TN: normal tissue, TT: tumour tissue, SN: normal serum, ST: tumour serum. P, Kaplan‐Meier curves for TCGA patients with KICH, KIRP and bladder cancer by the six‐snoRNA risk score. Q, ROC analysis of the sensitivity and specificity of the overall survival prediction for patients with KICH, KIRP and bladder cancer by the six‐snoRNA risk score
