Fig. 2From: Cilostazol improves endothelial function in acute cerebral ischemia patients: a double-blind placebo controlled trial with flow-mediated dilation techniqueCorrelation between initial serum L-arginine levels and FMD at enrollment and at 3Â months. Blue dots denote FMD at enrollment (T0), and red dots denote FMD at 3Â months (T1). a In the aspirin group FMD values and L-arginine levels do not show correlation at T0 and at T1. b In the cilostazol group, T0 FMD values and L-arginine levels do not show correlation, but an inverse correlation between the two values is revealed at T1Back to article page
