Table 3 Prevalence and performance of hypometabolism patterns in discriminating DLB from ADD and PD patients

From: Brain glucose metabolism in Lewy body dementia: implications for diagnostic criteria

Prevalence (%) of hypometabolism patterns
  DLB-like AD-like PD-like
DLB 64/72 (88.9%) 8/72 (11.1%) 0/72 (0%)
ADD 3/60 (5%) 57/60 (95%) 0/60 (0%)
PD 5/36 (13.8%) 0/36 (0%) 31/36 (86.1%)
Discriminative performance of hypometabolism patterns
  Sensitivity Specificity Accuracy
DLB vs. ADD 0.89  (0.79–0.95) 0.95 (0.86–0.99) 0.92 (0.86–0.96)
DLB vs. PD 1 (0.94–1) 0.86 (0.70–0.95) 0.95 (0.89–0.98)
