CXCL1 and non-small cell lung carcinoma: Our results of meta-analysis indicated that higher expression of mRNA CXCL1 was strongly correlation with worse OS whether it is in NSCLC (HR: 1.22, 95%CI: 1.07–1.40, P = 0.962, and I2 = 0.0%) (Figure 5A) or ADC (HR: 1.27, 95%CI: 1.07–1.49, P = 0.643, and I2 = 0.0%) (Figure 5B) or SQC (HR: 1.36, 95%CI: 1.01–1.84, P = 0.982, and I2 = 0.0%) (Figure 5C).
