There was no statistically significant correlation between RQ values of STAT5A and the clinical features of NSCLC patients, i.e., patients' age (P = 0.48), gender (P = 0.54), and history of smoking assessed as PY (P = 0.87), as well as histopathological features of tumor, i.e., pTNM classification (P = 0.34), AJCC classification (P = 0.83), NSCLC subtypes (SCC vs NSCC, P = 0.62) (ANOVA Kruskal-Wallis test, U Mann-Whitney's test followed by Spearman's rank correlation coefficient). This evidence concerns the gene STAT5A and non-small cell lung carcinoma.
