SNORA7B expression in breast cancer (BC) tissues and its clinical significance. a, b SNORA7B is upregulated in BC compared to both normal and adjacent normal tissues in TCGA dataset (p < 0.0001 and < 0.001, Mann–Whitney U test, Wilcoxon signed-rank test, respectively. c SNORA7B was overexpressed in breast cancer tissues compared to matched non-tumor tissues in our local cohort (p < 0.01, paired sample t-test). d Receiver operating characteristic (ROC) curve analysis of SNORA7B (p < 0.0001; AUC:0.84). e Kaplan–Meier plots of overall survival (OS). Patients with higher levels of SNORA7B exhibited poorer survival (p = 0.002, log-rank test)
