Time-frequency region for overall electroencephalography (EEG) coherence in the smoker group and interaction results between two groups. (A) The significant region indicated that the overall EEG coherence in the smoking condition was greater than that in the neutral condition during the smoking cue reactivity task. The p values were corrected with the false discovery rate. Log transformation was applied on the y-axis frequency. (B) The interaction results on the average EEG coherence of selected time-frequency region between two groups. **p < 0.01, ***p < 0.001, ns: not significant.
