Statements and results from the Delphi process for items reaching consensus or strong consensus: predictive factors of surgical failure

11	Surgical failure in OSA can be attributed to multiple factors, including the incorrect patient selection, surgical planning, or postoperative care	8,65	0	I
12	Severity of the disease might be associated with a higher risk of surgical failure	7,35	1	I
14	Patient’s higher BMI increase the risk of a surgical failure	8,32	0	II
15	Advanced age is associated with an increased risk of surgical failure	7,1	1	II
16	Multilevel airways sites of obstructions increase the risk of a surgical failure, regardless of the type of surgery performed	7,4	0	II
17	The choice of surgical approach based on the patient's anatomy reduce the surgical failures	7,62	1	I
18	The preoperative DISE evaluation, identifying sites and pattern of collapse/obstruction, could reduce a possible surgical failure	7,54	1	II
20	The surgeon's experience and skills play a crucial role in reducing surgical failures	8,12	0	I
21	The choice of a surgical treatment agreed upon by a multidisciplinary team could reduce the risk of a surgical failure	7,19	1	I
