The urinary angiotensinogen-to-creatinine ratio in patients who met the outcome renal replacement therapy or death compared to patients who did not. (A) Box and whisker plots show the median and interquartile range. Error bars represent the 5th and 95th percentiles. (B) A receiver operator characteristic curve was performed to evaluate the ability of the angiotensinogen-to-creatinine ratio (uAnCR) to predict the outcome renal replacement therapy (RRT) or death. The area under the curve (AUC) was 0.73.
