Similarly, statistical analysis concerning STAT5B did not reveal significant correlations between its expression levels and patients' age (P = 0.59), gender (P = 0.45), history of smoking (P = 0.66), NCSLC subtypes (P = 0.85) and tumor AJCC staging (P = 0.23) (ANOVA Kruskal-Wallis test, U Mann-Whitney's test followed by Spearman's rank correlation coefficient). This evidence concerns the gene STAT5B and neoplasm.
