a The hemoglobin effect on the difference between GEM and VITROS: relationship between hemoglobin and the difference in bilirubin estimated by the two methods. The solid line indicates the additive model fit, and the dashed lines indicate the 95% confidence intervals. b. The hemolysis effect on the difference between GEM and VITROS: relationship between hemolysis (H index) and the difference in bilirubin estimated by the two methods. The solid line indicates the linear model fit, and the dashed lines indicate the 95% confidence intervals
