Determinations of the cutoff point for maximum standardized uptake value at 60 min (SUVmax1) and ΔSUVmax% with reference to relapse events. (a) Receiver operator characteristic (ROC) curves of SUVmax1 for relapse-free survival (n = 464). SUVmax1 at the cutoff value was 3.4, area under the curve (AUC) was 0.627 (95% CI: 0.536–0.719). (b) ROC curves of ΔSUVmax% for relapse-free survival (n = 464). At the ΔSUVmax% cutoff value of 12.5, AUC was 0.594 (95% CI: 0.505–0.683)
