Abstinence rates during the follow-up period according to the presence and absence of ASD or ADHD traits. Graph A: ASD traits assessed using the AQ scores (p = 0.7537, log-rank test; p = 0.9857, Wilcoxon test). The number of subjects with ASD traits was 29, while the number of subjects without ASD traits was 461. Graph B: ADHD traits assessed using ASRS part A (p = 0.0817, log-rank test; p = 0.0296, Wilcoxon test). The number of subjects with ADHD traits was 88, while the number of subjects without ADHD traits was 426. Graph C: ADHD traits divided into three classes by using the total endorsed number of ASRS part A and part B (p = 0.0995, log-rank test; p = 0.0397, Wilcoxon test). The number of subjects with ADHD traits was 76, while the number of subjects without ADHD traits was 438
