2. Fig 1
Univariate correlation between serum S100β level (μg/L) and cerebral emboli during the time period (time 2) from aortic cannulation to aortic cross-clamp onset (p = 0.022, r = 0.218). Both the x-axis and y-axis are depicted on natural log scales because of the positively skewed data.

3. Fig 2
Univariate correlation between serum S100β level (μg/L) and age (years) (p = 0.002, r = 0.248). The y-axis is depicted on a natural log scale because of the positively skewed data.

4. Fig 3
Univariate correlation between serum S100β level (μg/L) and cross-clamp time (min) (p = , r = 0.406). The y-axis is depicted on a natural log scale because of the positively skewed data.
