Fig. 2. (A) Scattergram with Passing-Bablok regression and (B) Bland-Altman plot showing the results of comparison between Norudia GA (modified) and Lucica GA-L, and (C) Scattergram with Passing-Bablok regression and (D) Bland-Altman plot showing the results of comparison between Norudia GA (original) and Lucica GA-L. The solid navy blue line indicates the fitted Passing-Bablok regression, and the blue-colored area represents the 95% CI. In the Bland-Altman plots, the solid black line indicates the mean % difference, and the dashed lines represent the 95% CI. The red dots indicate the samples with negative interference demonstrating a % difference of <-14.4% between the original version of the Norudia GA and Lucica GA-L assays.
