Summary

This study tracked 582 children aged 6 to 18 who had surgery to see how many still had pain 3 months later. Researchers used a pain questionnaire to measure pain levels and identify risk factors. The goal was to better understand chronic post-operative pain in kids, not to test any treatment.
