Figure 1. Mutational frequency rates of eight candidate single nucleotide polymorphisms in patients with non-small cell lung cancer (NSCLC) and bone metastasis. Classification analysis of SNP genotypes based on mutation and wildtype. (A) Analysis of SNPs in all 500 patients with NSCLC, including bone metastasis. (B) Analysis of SNPs in 105 patients with bone metastasis from NSCLC.
