From: Platelet-derived growth factor predicts prolonged relapse-free period in multiple sclerosis
Influence of CSF PDGF levels on clinical and radiological disease activity. a The probability to not reach a clinical relapse, the RFS, according to the PDGF group. RFS was higher in both “medium PDGF” and “high PDGF” groups compared to patients with “not detected PDGF”. b The probability to not reach the first MRI progression during the observational period, the MRI progression-free survival in the three PDGF groups. No significant difference was found in the three PDGF groups
