  1. Whole-brain vertex-wise analyses. Vertex-wise p < 0.05, corrected for multiple comparisons using Monte Carlo Null-Z Simulation (5000 times, cluster p < 0.05). (+) or (−) showed positive or negative correlation respectively
  2. a ANCOVA with sex, age and total intracranial volume (ICV) controlled
  3. b Partial correlation with sex, age, age at onset of methamphetamine (MA) use, duration of MA use (MA use) and ICV controlled
  4. c Partial correlation with sex, age, age at onset of MA use, duration of abstinence from MA (ABS) and ICV controlled
