Kaplan-Meier survival curve illustrating the prognostic significance of PAK4 expression in NSCLC. a: The patients (n = 210) were divided into high or low PAK4 expression groups according to the proportion of positively stained tumor cells and staining intensity. 5 year survival was calculated using the Kaplan-Meier method and analyzed using the log-rank test. b: 5 year survival was calculated only in the stage I + II cancer patients. c: 5 year survival was calculated only in the stage III + IV cancer patients
