There was a positive relationship between the severity of stroke at D1 according to the National Institutes of Health Stroke Scale, and ADEV AQP4 at D1 (r = 0.50, p = 0.031), as well as ADEV GDNF at D1 and D7 (r = 0.49, p = 0.035 and r = 0.53, p = 0.021, respectively). This evidence concerns the gene GDNF and stroke disorder.
