Fig 1: Content of CEACAM1, NGAL and MMP-9 in the plasma of patients with IS. (A) Comparison of plasma CEACAM1 concentration in the IS patients and healthy control. (B) Correlation analysis between plasma CEACAM1 content and percentage of CEACAM1 positive neutrophils in the subacute group. (C, D) Comparison of plasma MMP-9 and NGAL in the IS group and the healthy control group. A post hoc test or Kruskal–Wallis was utilized for the analysis. CEACAM1, carcinoembryonic antigen-related cell adhesion molecule 1. NGAL, neutrophil gelatinase-associated lipocalin. MMP-9, matrix metalloproteinases-9. IS, ischemic stroke
