In consideration of the gene expression data of the KMplotter database from different microarray analysis platforms, we analyzed the clinical significance of SOX30 mRNA expression with Kaplan-Meier Plotter in human lung cancers from three selected cohorts: the TCGA dataset (Figure S1C, HR = 0.31, p = 0.0075), GSE19188 dataset (Figure S1D, HR = 0.4, p = 0.0023) and GSE4573 dataset (Figure S1E, HR = 0.41, p = 0.0028) respectively. This evidence concerns the gene SOX30 and lung cancer.
