Fig 1: Associations between the expression of podoplanin and FGF1, and overall survival of patients with lung squamous cell carcinoma. (A) Differences in the overall survival rates of podoplanin-positive and podoplanin-negative patients were analyzed. (B) Differences in the overall survival rates of FGF1-positive and FGF1-negative patients were analyzed. (C) Differences in the overall survival rates among P+F+, P+F-, P-F+ and P-F- patients were analyzed. P+F+ had a significantly lower survival rate compared with the P-F- group. PDPN, podoplanin; FGF1, fibroblast growth factor 1; P+F+, podoplanin-positive/FGF1-positive; P+F-, podoplanin-positive/FGF1-negative; P-F+, podoplanin-negative/FGF1-positive; P-F-, podoplanin-negative/FGF1-negative.
