Fig. 3From: Clinical outcomes in central nervous system solitary-fibrous tumor/hemangiopericytoma: a STROBE-compliant single-center analysisKaplan-Meier survival curves display over all-survival and progression-free survival with different EOR and WHO grade. Figures exhibited EOR (a, b) and WHO grade (c, d)-related overall-survival and progression-free survival. EOR and WHO grade in PFS were statistically significant with p-value equaling 0.024 and 0.017. GTR, gross total resection; STR, subtotal resectionBack to article page
