Disease-free survival (DFS) relevant statistics in Figure 2B revealed a linkage between poor prognosis and high XRCC1 gene expression levels for the cancer cases from the TCGA dataset of LGG (n=521, P=0.024), LIHC (n=364, P=0.0053) and LUAD (n=478, P=0.034). The gene discussed is XRCC1; the disease is cancer.
