Kaplan-Meier plots of overall survival duration in patients with NPC. MMP9 protein expression in NPC and NP samples(A-E): A:Weak expression of MMP9 in NP sample; B:Negative expression of MMP9 in NPC samples(original magnification 400×);C-E:Strong staining of MMP9 in NPC samples (original magnification 400×). F. Kaplan-Meier survival analysis of overall survival duration in 164 NPC patients according to MMP9 protein expression. The log-rank test was used to calculate p values.
