---|---|---|---|---|---|---|
PAD, short | 170 ± 18 | 743 ± 77 | 95.5 ± 1.1 | 54.6 ± 4.1 | 1.77 ± 1.63 | 0.89 ± 2.11 |
PAD, long | 211 ± 25 | 632 ± 120 | 96.8 ± 1.8 | 51.9 ± 2.4 | 1.78 ± 1.81 | 2.23 ± 1.85 |
HC, short | 168 ± 25 | 593 ± 166 | 96.1 ± 1.7 | 50.7 ± 3.2 | 2.08 ± 1.11 | 1.26 ± 1.85 |
HC, long | 222 ± 22 | 597 ± 138 | 96.9 ± 1.9 | 51.1 ± 1.8 | 2.46 ± 2.09 | 1.58 ± 1.17 |
P value, Interaction effect | 0.327 | 0.131 | 0.623 | 0.076 | 0.703 | 0.322 |
Note: PAD: patients with alcohol dependence; HC: healthy controls; %go and %stop: percentage of successful go and stop trials; SSRT: stop-signal reaction time; PES: post-error slowing; all numbers are mean ± standard deviation. P values of the interaction effect are all based on 2-way ANOVA: subject by SSRT group.
