Ranked according to relative risk of unfavourable outcome. Fisher exact test was performed to determine significance. Sens (sensitivity), spec (specificity), PPV (positive predictive value), NPV negative predictive value. Change (change from baseline), intensified (at least one intensified or new lesion), month 6 (M6), percentage change from baseline to M6 (change), total glycolytic activity index (TGAI), composite TGAI (TGAIcom), cavity wall thickness (Cavwall), total abnormal density volume (Vtotal)
