  1. aResults of multivariate analysis examining survival function of patients with tumors with any squamous morphology or immunoprofile.
  2. bThese results refer to the relationships between sex and FGFR1 amplification, and smoking and FGFR1 amplification, respectively, and were only significant when examined in all non-small cell lung carcinoma patients; significance was lost when only patients with tumors with any squamous morphology or immunoprofile were examined.
