STK11 and non-small cell lung carcinoma: Additionally, data from Kaplan-Meier plotter showed that high expression of STK11 was a significant protective factor for NSCLC patients, both in terms of PFS (HR=0.74, 95%CI= (0.60-0.92), P=0.007) and OS (HR=0.76, 95%CI= (0.65, 0.88), P<0.001) (18), as shown in Figures 4A, B.
