**Figure 2.** (**A**) The heatmap of the correlations between the lncRNAs and SARS-CoV-2 related genes. (**B**) The heatmap of correlations between the lncRNAs and m^{6}A related genes. (**C**) Histogram based on maximally selected rank grouping. (**D**) The cut-off point with the maximum standard log-rank statistic was marked with a vertical dashed line. (**E**) The box plot showed the difference of F2RL1, FBLN5, NINL and SLC27C between low-risk group and high-risk groups. (**F**) The expression profiles of DEGs between the low-risk group and high-risk groups. (**G**) Forest plot of 9 DEGs with P < 0.01 by univariate Cox regression. (**H**) The heatmap of the correlations between three DEGs and 4 immune cells. (**I**) The box plot showed the significant difference of the immune cell infiltration between two groups.
