The results showed that NCAPG expression can be used to predict OS in breast cancer (P < 0.01; Figure 6A), RFS (P < 0.01; Figure 6B), PPS (P < 0.01; Figure 6C), DMFS (P < 0.01; Figure 6D), liver cancer, PFS, PFS, and DSS (P < 0.01; Figure 6E), lung cancer (P < 0.01; Figure 6F), FP (P < 0.01; Figure 6G), and PPS (P < 0.01; Figure 6H), gastric cancer (P < 0.01; Figure 6I), FP (P < 0.01; Figure 6J,), and PPS (P < 0.01; Figure 6K). This evidence concerns the gene NCAPG and lung cancer.
