FGF2 and melanoma: Using GEE models, or regression models when GEE could not be reliably fit, only bFGF digital H-score from the melanoma compartment was significantly positively associated with intratumoral hemorrhage (coeff = +5.74, p=0.02, Figure 4A, yellow arrows) and significantly negatively associated with TILs (coeff = -5.70, p=0.009).
