Kaplan-Meier estimates and the number of cases of the genotype groups for the GBM survival analysis.

Dashed lines illustrate 0.95 confidence intervals for each group in the analysis. Panel a) rs2275565 is a tag-SNP to the coding SNP rs1805087 in the MTR gene. The group of 11 homozygous cases with AA genotypes is combined with the heterozygous group. Panel b) rs100192 is a tag-SNP to a SNP rs164390 in 5′ UTR of the CCNB1 gene.
