Asymmetric Dimethylarginine and Progression of Chronic Kidney Disease - a One-Year Follow-Up Study Kidney Blood Press Res 2014;39:50-57 - DOI:10.1159/000355776 Fig. 1. Interaction of baseline eGFR with ADMA (A) and AOPP (B) in relation to eGFR change per year (n = 164, patients with complete, one-year follow-up). Numbers on the left and right side of eGFR quartiles denote counts of patients belonging to the quartile above and below median of appropriate variable (ADMA or AOPP). A. Graphic representation of interactions reveals that patients with baseline eGFR in the highest quartile (> 36 mL/min/1.73m2) with ADMA levels higher than median (0.87 µmol/l) had the most severe decline of eGFR. B. In the case of AOPP, interaction of baseline eGFR higher than median (> 24 mL/min/1.73m2) with AOPP levels higher than median (142 µmol/L) predicted the highest decrease in eGFR. © 2014 S.
