Video Versus Face‐To‐Face Preoperative Anaesthetic Assessment: The VIDFACE Trial—A Statistical Analysis Plan
Study context
- Population
- Adults undergoing elective ear-nose-throat or oral and maxillofacial surgeryplanned enrolment
- Participants
- 2,260 adults
- Planned comparison
- Video-based vs face-to-face preoperative anaesthetic assessment
- Primary endpoint
- Composite of five predefined serious complications
Methodological detailsmulticentre, two-arm, superiority, assessor- and data analyst blinded, stratified 1:1 randomisation, planned interim analysis, Assumed 30% relative risk reduction of the primary composite outcome, Interim analysis after inclusion and follow-up of half the intended sample size, Two blinded statisticians; two abstracts written before unblinding (A as intervention, and the opposite)
