Comparison of Hepatic Collagen Kinetics and Histologic Fibrosis Score.

<p>(A) Linear regression of hepatic type I collagen FSR (% new per day) and histopathologic fibrosis score in human subjects with chonic liver disease. (B,C) Bar graphs depicting the relative abundance of unlabeled (old) and labeled (new) hepatic type I collagen (B) and type III collagen (C) per unit mass of liver protein, normalized to 30 days of labeling <i>in vivo</i>. Collagen FSR values (% new per 30 days) are displayed above each bar. Values shown represent the subject or the mean of subjects with each histopathology score. Abbreviation: fractional synthesis rate (FSR).
