Correlation analysis between medication status and other clinical variables only showed a significant association with disease duration (r = −0.094; pcorrected < 10−05; Bonferroni-corrected). We therefore performed additional medication status classifications after splitting patients for disease duration (e.g., HC vs. medicated + short duration OCD; HC vs. unmedicated + short duration OCD, etc.). Classifications with or without splitting patients for disease duration were comparable (see supplementary Tables S7(a–c) for full overview).
