Figure 3.
Correlations between urinary excretion rates (ng/min) of adenosine (A), inosine (B), guanosine (C), adenosine + inosine (D), adenosine + guanosine (E) and adenosine + inosine + guanosine (F) versus creatinine clearance. The summation of the excretion rates of adenosine + inosine + guanosine (F) yielded the strongest positive correlation with renal function. Red symbols represent data from patients with acute kidney injury.
