Correlation of the international prognostic index (IPI) and the pretreatment phosphatemonoester/nucleoside triphosphate per patient in the whole non-Hodgkin lymphoma cohort. The long-term response to treatment outcome of each patient was also plotted as CR, complete response (filled circles) and noncomplete responders (open circles). Tumors were stratified on the basis of the IPI as low grade (L), low-to-intermediate (LI), high-to-intermediate (HI) and high-grade (H) tumors. A line was drawn between the medians of the L and LI points and extended through the HI and H columns. This line was a useful threshold for predicting failure to exhibit a CR.
