Association between the pain NRS scores and ASRS or AQ screening positivity rates in the entire cohort, non-CP symptoms group, and CP symptoms group. The width of each pain NRS grade on the horizontal axis represents the proportion of individuals who reported that grade of pain. The ASRS screening positivity rate increases significantly with increasing pain NRS score, especially for grade 5 in the CP group, with a positivity rate of 38.3%. ADHD, attention deficit/hyperactivity disorder; AQ, autism spectrum quotient; ASD, autism spectrum disorder; ASRS, adult ADHD self-report scale; NRS, numerical rating scale; CP, chronic pain.
