PDCD1 and non-small cell lung carcinoma: The result shows that the AC027288.1 gene (R = −0.44, p < 0.001, Figure 10B) and PDCD1 (R = −0.18, p < 0.001) displayed a negative correlation with risk score, which indicating that AC027288.1 and PDCD1 might both act as protection in the prognosis of NSCLC (Figure 10C).
