Log correlation plot capillary 1 and capillary 2 S100B. Sixty-one matched samples. Positive numbers with unit μg/l are corresponding non-logarithmized values for illustrational purposes. Pearson’s correlation coefficient = 0.70 (p < 0.05). Regression line: intercept = − 0.24 (95% confidence interval − 0.42 to 0.06). Slope 0.77 (95% confidence interval 0.56–0.97). R2 = 0.49
