Regression analysis. The figure shows the scatter plot with regression line (green line), CI95% curves (red lines) and equality line (black line) for SpHb/Lab data pairs (56 pair measurements). As noted, SpHb underestimated the value of Hb provided by the laboratory. Linear regression analysis reported a correlation coefficient of 0.8960 (CI95% 0.8281-0.9379, p value < 0.0001). Regression equation was: Lab = 1.6882 + 0.9728 × SpHb
