**Figure 1.** **Overview of differentially expressed ncRNAs and mRNAs.** (**A**) Overview of the analysis pipeline. (**B**–**D**) Hierarchical cluster analysis of significantly upregulated and downregulated ncRNAs and mRNAs. Each column represents a sample and each row represents an ncRNA or mRNA. Red represents high relative expression and blue represents low relative expression. (**E**–**G**) Volcano plots were used to visualize differential expression after SCI. The red and blue points represent upregulated and downregulated ncRNAs and mRNAs, respectively, with statistical significance. Significance was defined as *p* < 0.05.
