Fig 2: Violin plot in the distribution of YKL-40 between SAP group and non-SAP group.

Fig 3: Correlation between YKL-40 and mRS score. YKL-40 showed a significant relationship with modified Rankin Scale (mRS) score. (r=0.343, P<0.001, and Spearman rank correlation analysis).

Fig 4: Serum YKL-40 levels in different groups according to (A) poor outcome, (B) all-cause mortality and (C) recurrent stroke in AIS patients. Mann-Whitney U Test. Horizontal lines represent medians and interquartile ranges (IQRs).

Fig 5: Serum YKL-40 levels in different groups according to (A) overall WMH, (B) PV-WMH and (C) D-WMH in AIS patients. Horizontal lines represent medians (IQR).
