MicroRNA (miR)‐92b‐3p is upregulated in clear cell renal cell carcinoma (ccRCC) and inversely correlates with patient overall survival (OS). A, miR‐92b‐3p expression in ccRCC tissues. Expression of miR‐92b‐3p was examined in 20 matched‐pair samples of ccRCC by quantitative real‐time PCR. Data are the relative expression normalized to U6 snRNA. Comparison was undertaken by Mann‐Whitney U test. ***P < .001. B, Probability estimates of OS of patients. ccRCC samples were divided into 2 groups, high or low levels, based on real‐time PCR results. Kaplan‐Meier survival estimates stratified by miRNA level. Statistical analysis was carried out using the Gehan‐Breslow‐Wilcoxon test
