The analysis revealed high correlation within FGFR1, FGFR2, and FGFR3 expression assessed with both methods (r = 0.77, p = 0.000001; r = 0.86, p = 0.000001; and r = 0.95, p = 0.000001, respectively; Figure 2 and Supplementary Figure S2) in 40 Sq-NSCLC tumor samples. Here, FGFR3 is linked to non-small cell lung carcinoma.
