Correlation between GPX4 expression and the survival of patients based on the LUAD tissue microarray. (A) Representative images of different immunohistochemical staining intensities of GPX4 in the LUAD tissue microarray: (a) negative staining; (b) weak staining; (c) moderate staining; (d) strong staining. Scale bar =200 µm. (B) Different GPX4 expression between LUADs and normal lung tissues. Cox regression analysis of GPX4 in LUADs from the tissue microarray. (C) The Kaplan-Meier survival curve showed that LUAD patients with low GPX4 expression had an unfavorable OS (P=0.0228). (D) Univariate analysis. (E) Multivariate analysis. High, high expression; Low, low expression; HR, hazard ratio.
