EGFR and squamous cell carcinoma: Additionally, the DLS was positively correlated with SUVmax (Spearman’s rho=0.43, p<0.001), squamous cell carcinoma (SCC) (point-biserial rhopb=0.27, p<0.001), male sex (point-biserial rhopb=0.19, p<0.001), smoking status (point-biserial rhopb=0.20, p<0.001), and negatively correlated with EGFR status (point-biserial rhopb=−0.20, p<0.001) for the whole SPH cohort.
