a–c Time courses of ADMA, SDMA, and L-arginine in acute ICH. Data are presented as median (interquartile range). Values in controls are presented by dashed line. Differences between patients and controls: *** p ≤ 0.001. Within group comparisons of marker levels between initial (≤ 24 h) and follow-up time points: significant differences were detected for ADMA (≤ 24 h versus 7 days; p = 0.030) and SDMA (≤ 24 h versus 3 days; p = 0.029)
