Primary resultResult — go to the resultOdds ratio 0.33 95% CI 0.18–0.61Authors' conclusion
Preoperative simulation training reduced the incidence of short-term negative postoperative behavioral changes and improved perioperative psychological outcomes in children who underwent tonsillectomy and adenoidectomy

- Comparison
- Video-guided preoperative simulation training vs preoperative visit only
- Primary endpoint
- Cumulative incidence of negative postoperative behavioral changes
- Follow-up
- First 28 postoperative days
