Fig. 2. Regression lines (A and B) and Bland–Altman plots (C and D) of eGFR values between Gentian_eq and CKD-EPI_cys using cysC values with Gentian_cys and Roche_cys. The Y-axes of (C) and (D) are the differences in eGFR between Gentian_eq and CKD-EPI_cys.
Abbreviations: eGFR, estimated glomerular filtration rate; cysC, cystatin C; Gentian_cys, Gentian cystatin C immunoassay; Roche_cys, Tina-quant Gen.2 analysis; Gentian_eq, equation of Gentian manufacturer; CKD-EPI_cys, CKD-EPI cystatin C equation.
