Table 1.

A significant correlation between the overall COWS scores changes and the normalized max PSD occurred during the LOC for “Sinusoidal Patients” with positive COWS scores, indicating deterioration of “Sinusoidal Patients” with positive COWS scores temporally.

	N	Δ COWS Scores a	Normalized Max PSD b	Pearson’s R	p-Value
FOC c	5	5.40 ± 3.29	0.11 ± 0.02	0.20	0.74
LOC d	5	5.60 ± 3.05	0.11 ± 0.02	0.92	0.03

^a Δ COWS Scores = change in clinical opiate withdrawal scale; ^b Normalized Max PSD = normalized maximum power spectral density; ^c FOC = first opioid cue; ^d LOC = last opioid cue.
