  1. Because pairwise group comparison analyses involved three statistical tests (one per OFC subtype), we used a Bonferroni-corrected significance threshold of 0.05/3 = 0.017
  2. Statistically significant results (i.e. p < 0.017) are displayed in bold
  3. PGs pathological gamblers, HCs healthy controls, BF Bayes Factor, L left, R right
  4. aAnalyses comparing the distribution of OFC sulcogyral patterns between PGs and HCs in the present study
  5. bData from the HCs (N = 50) of Chiavaras and Petrides (2000) are included in the table for ease of comparison
