To explore the association between the mRNA expression of LDHA and survival in NSCLC patients, Kaplan–Meier plotter database was utilized, which generated gene expression and clinical data from a total of 1928 NSCLC patients, from the following databases: CaArray, GSE14814, GSE19188, GSE29013, GSE30219, GSE31210, GSE3141, GSE31908, GSE37745, GSE4573, and GSE50081. Here, LDHA is linked to non-small cell lung carcinoma.
