At multivariate analysis, major vascular invasion and rs1870377 were independent factors in TTP and performance status, rs1870377, and rs2071559 were independent factors in OS.
Three SNPs, rs2071559, rs7667298 and rs2305948, showed a statistically significant increased association with the risk of glioma (P = 0.006, 0.005, and 0.012, respectively).
Compared with their corresponding wild-type genotypes, one coding variant, rs2305948 (Val297Ile), in the vascular endothelial growth factor receptor-2 gene was associated with increased susceptibility to intracerebral hemorrhage (additive model: OR, 2.06; 95% CI, 1.64 to 2.59; P=7.6x10(-10); dominant model: OR, 2.20; 95% CI, 1.70 to 2.84; P=1.5x10(-9)), a promoter variant rs2071559 (-604T>C) in the gene was associated with reduced susceptibility to atherothrombotic stroke (additive model: OR, 0.82; 95% CI, 0.71 to 0.93; P=0.003; dominant model: OR, 0.78; 95% CI, 0.65 to 0.92; P=0.004) and was reversely correlated with carotid artery intima media thickness (P=2.8x10(-5)).
