ITPKA hyper expression predicts poor prognosis in LUAD. 92 patients were enrolled in the multivariant cox regression survival analysis. A, compared with tumor samples the normal samples have lower ITPKA level in IHC. B, the K-M plot form http://kmplot.com indicates that ITPKA is negatively corelated with LUAD patients survival, HR=1.68(1.33-2.13). C, the forest plot of multivariant cox regression analysis shown TNM stage, N stage, pathology, age and ITPKA level could serve as independent indicators for survival (data in Table S1). D, ITPKA staining score was positively corelated with prognosis (HR= 2.467(1.16-5.25), p=0.03, multivariant cox regression).
