Kaplan-Meier survival analyses of high grade astrocytomas. a Survival patterns in patients with WHO grade IV (n = 56) compared to those with WHO grade III (n = 21) high-grade astrocytomas (p = 0.0001, by log-rank test). b Patterns of patients with high EMMPRIN (>1,500, n = 36) versus low EMMPRIN (<1,500, n = 41) expressions (p = 0.7274, by log-rank test). c Patterns of patients with high EMMPRIN (>2,000, n = 19) versus intermediate high (n = 39) and low EMMPRIN (<1,000, n = 19) expressions (p = 0.6981, by log-rank test)
