Bland-Altman plot. The figure shows Bland-Altman plot for SpHb/Lab data pairs, with accuracy/mean line (blue line), upper and lowest LOA (accuracy ± 1.96 SD or precision, dashed red line), CI95% (vertical blue bars). Bland-Altman analysis between SpHb and Lab values showed that SpHb accuracy was −1.37 g/dL (CI95% −1.51 to −1.22 g/dL, p value < 0.0001), with a precision of 0.55 g/dL, lower LOA −2.45 g/dL (CI95% −2.71 to −2.20 g/dL) and upper LOA −0.28 g/dL (CI95% −0.53 to −0.02 g/dL)
