Fig. 5From: Construction of a circular RNA-based competing endogenous RNA network to screen biomarkers related to intervertebral disc degenerationValidation of differential expression of miRNAs in the ceRNA network in independent dataset. Expression levels of three miRNAs in GSE63492 (A) and GSE19943 (B). The difference of expression level (log2 transformed expression) was compared between control (CTRL) group and IDD group by student’s t test. * represents P < 0.05Back to article page
