Heatmap of correlations between lncRNAs (NRAV, AL031985.3) and m6A-related genes in HCC. Among the m6A-related genes, blue represents “writers”, green represents “Reader”, and red represents “erasers”. In the correlation heatmap, red represents a positive correlation between lncRNAs and m6A-related genes, and blue represents a negative correlation. The darker the color, the stronger the correlation. “∗” means Pvalue<0.05, “∗∗” means Pvalue<0.01, “∗∗∗” means Pvalue<0.001.
