Scatter dot plots of MALAT1 levels in NSCLC (N = 45), AdCa (N = 21), SqCC (N = 24), and cancer-free controls (N = 25). Expression values were normalized by the geometric mean of GAPDH and HPRT1 and expressed as ΔCt. Horizontal bars represent median and IQR. Groups were compared using the Kruskal-Wallis test. NSCLC: non-small cell lung cancer, AdCa: adenocarcinoma, SqCC: squamous cell carcinoma.
