Table 3. Performance of conventional criterion (2 μmho/30 sec criterion) to classify hot flashes from sternal skin conductance by obesity status.

Referent: expert-defined hot flashes Referent: subject-reported hot flashes
Normal
(N=10)		 Overweight
(N=7)		 Obese
(N=14)		 Normal
(N=10)		 Overweight
(N=7)		 Obese
(N=14)
Sensitivity 0.75 0.63 0.41 0.69 0.68 0.32*
Specificity 0.98 0.99 0.99 0.86 0.91 0.96*
PPV 0.94 0.93 0.86 0.51 0.64 0.63
NPV 0.93 0.90 0.88 0.96 0.93 0.88*
F1 0.77 0.68 0.44 0.53 0.60 0.30

Note: Normal weight BMI <25 (referent), Overweight BMI 25-29.9, Obese BMI ≥30; Low state anxiety ≤27.5 (referent), high state anxiety >27.5; N's are as noted except PPV for expert-defined hot flashes referent (normal weight N=9, overweight N=6, obese N=9) and PPV for subject-reported hot flashes referent (normal weight N=9, overweight N=6, obese N=8)
