Kaplan–Meier curve of progression-free survival time (PFS) (A) and overall survival time (OS) (B) in patients with glioblastoma (GBM) showed prognostic significance of gelsolin (GSN). GBM patients were classified into two categories on the basis of GSN level: low (0–472 fmol/μL plasma) and high (> 472 fmol/μL plasma). Mean GSN plasma level in GBM patients was selected as the cut-off point. (A) PFS interval was determined as the interval between the date of initial operation and the date of patient’s recurrence or determined endpoint (for those no recurrent on August 1, 2015). (B) OS interval was determined as the interval between the date of the initial operation and date of patient’s death or determined end point (for those alive on August 1, 2015).
