Based on the AUC of 0.825, FFA showed a markedly greater discriminatory ability when compared with the Hs-CRP (AUC, 0.668; 95% CI, 0.601–0.738; P < 0.001), the NIHSS score (AUC, 0.744; 95% CI, 0.667–0.811; P < 0.01), and infarct volume (AUC, 0.584; 95% CI, 0.503–0.665; P < 0.0001). Here, CRP is linked to infarction.
