Fig. 1.
Differences in asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) concentrations in serum of adult autosomal dominant polycystic kidney disease (ADPKD) patients with higher total kidney volume (TKV) but preserved estimated glomerular filtration rate (eGFR) >60 ml·min−1·1.73 m−2 (A) and comparison between healthy subjects and ADPKD patients with preserved and moderately reduced eGFR (B). Values are means ± SD. Significance levels: *P < 0.05, **P < 0.01, ***P < 0.001 vs. TKV < 800 ml (A) and vs. healthy subjects (B). For significance levels between the ADPKD patients with preserved and moderately reduced eGFR, please refer to Table 4.
