Kaplan–Meier curve analysis of overall survival probabilities of patients with lung adenocarcinoma based on G9A and CASP1 expression. (a) Kaplan–Merier survival analysis of LUAD patients based on G9A expression. Red line: high G9A expression; black line: low G9A expression. Numbers at risk for each time point were listed below time points. (b) Kaplan–Merier survival analysis of LUAD patients based on CASP1 expression. Red line: high CASP1 expression; black line: low CASP1 expression. (c) Kaplan–Merier survival analysis of LUAD patients based on both G9A and CASP1 expression. LUAD patients were divided into four groups: low G9A and high CASP1 expression (green line), high CASP1 and CASP1 expression (blue line), low G9A and CASP1 expression (purple line), and high G9A and low CASP1 expression (red line). P-values (from the log-rank test) were calculated using the group of high G9A and low CASP1 expression as the reference group.
