Figure 4From: Identification of hypoxanthine as a urine marker for non-Hodgkin lymphoma by low-mass-ion profiling Significant decrease of hypoxanthine and xanthine in NHL urine. The levels of hypoxanthine (HX) (A) and its oxidative product, xanthine (X) (B) were significantly lower in NHL urines (both P < 0.001). Area under the curve, sensitivity and specificity obtained from blind validation of 221 urines samples (125 control, and 96 NHL) are shown.Back to article page
