Log correlation plot venous and capillary 2 serum S100B protein level. Sixty-one matched values. Positive numbers with unit μg/l are corresponding non-logarithmized values for illustrational purposes. Pearson’s correlation coefficient of 0.41 (p < 0.05). Line of regression: intercept: − 1.07 (95% confidence interval − 1.21 to − 0.92). Slope = 0.28 (95% confidence interval 0.12–0.44)
