Bland–Altman analysis of hemoglobin measurement error. Bland–Altman plots for repeated measurements per participant comparing SpHb and laboratory hemoglobin concentrations in the normal (a), mild-to-moderate hyperbilirubinemia (b), and severe hyperbilirubinemia (c) groups. The mean bias (solid line) ± 95% confidence interval (dashed line) is displayed. SpHb non-invasive hemoglobin concentration.
