Elevated homocysteine as an independent risk for intracranial atherosclerotic stenosis
Figure 1. Compariation of Hcy concentration (μmol/L) and percentages of the third and fourth quarter of Hcy distribution according to the number of ICAS in ischemic stroke patients and non-stroke controls. Data are mean of Hcy concentration and percentages of patients in third and fourth quartiles. P value indicates the comparison among four groups with Kruskal–Wallis and Chi-squared test respectively. * P < 0.05 in comparison with those absent of ICAS. † P < 0.001 in comparison with those absent of ICAS. ‡ P<0.05 in comparison with those with one segment of ICAS.
