Comparison of C-FCM granulocyte PNH clone size results with three different GPI markers and HS-FCM. Results are compared using Passing-Bablok regression analysis (A-C) and Bland-Altman analysis (D-F). Regression equations, correlation coefficients, and 95% CIs for the slope and intercept of the equations are shown in (A-C). In the Bland-Altman analysis, mean difference (indicated by the blue horizontal line), lower and upper limits of agreement (indicated by the red dotted horizontal lines), and their 95% CIs (indicated by the cyan vertical bars) are presented in (D-F).

Abbreviations: HS-FCM, high sensitivity flow cytometry; C-FCM, conventional flow cytometry; PNH, paroxysmal nocturnal hemoglobinuria; FLAER, fluorescein-labeled proaerolysin; CD, cluster of differentiations; CI, confidence interval.
