What was measured

Surgery quality was evaluated based on grade 3-4 bleeding events per Common Terminology Criteria for Adverse Events (CTCAE) v5.0 during surgery and positive margins after surgery. Per CTCAE v5.0, grade 3 = severe and grade 4 = life-threatening. Having grade 3-4 bleeding or positive margins indicates worse outcomes.
