Significant cortical clusters identified in group comparisons or within-group correlation analyses. A. Greater thickness in methamphetamine (MA) users (n = 99) than healthy controls (n = 86). B. Positive correlation of duration of abstinence with cortical thickness in MA users. C. Negative correlation of duration of MA use with cortical thickness in MA users. D. Smaller volume in MA users than healthy controls. E. Positive correlation of duration of abstinence with gray-matter volume in MA users. F. Negative correlation of duration of MA use with gray-matter volume in MA users. Statistical methods were shown in the notes of Table 2. Color bar shows statistical significances. The threshold was set at vertex-wise p < 0.05 corrected for multiple comparisons using Monte Carlo Null-Z Simulation (5000 times, cluster p < 0.05)
