LCN2 and Stroke: In exploring the correlation between the prognosis of patients and assessing the severity of the stroke, the results showed that the expression levels of CRP and IL-6 in the serum of patients with ACI were positively correlated with mRS score (R = 0.374, p < 0.01) (R = 0.431, p < 0.01), but there was no correlation between NGAL expression level and mRS score (R = 0.112, p > 0.05).
