Fig. (2) Regression analysis of %SV correlated with neurological assessment scores (NAS). Combined data of both SD and SHR rats (n=39), in the controls (♦) indicate increasing %SV was associated with a positive correlation of increasing deficits at r=0.75, in the 1x DDFPe (symbol) correlation r=0.24, and in the 4x DDFPe (■) correlation r=0.58, both significantly different from control, p<0.01. This suggests a therapeutic effect of DDFPe.
