Bland-Altman plot venous versus capillary 2 serum S100B protein level. Sixty-one matched samples. Venous sample used on y-axis because the true value is assumed to be venous sample. Regression line: intercept = 0.05 (95% confidence interval 0.04–0.06). Slope 0.06 (95% confidence interval 0.01–0.12). R2 = 0.08
