Figure 5. The keratoconus (KC)-associated competing endogenous RNA (ceRNA) regulatory network. The squares, diamonds, and circles represent
long non-coding RNAs (lncRNAs), miRNAs, and mRNAs, respectively. Blue and red represent upregulation and downregulation, respectively.
Black lines and red lines represent, respectively, lncRNA–miRNA and miRNA–mRNA relationships. Purple triangles represent KC-associated
