Methodological Quality of the Included Studies
Supplemental Table 1 depicts NICE Quality Assessment and general characteristics of the studies included in this review. The studies included in the review were six retrospective and one prospective study. Five retrospective and one prospective study had data usable for meta-analysis pertaining to pre- and post- operative AHI. Four retrospective studies had data usable for meta-analysis for pre- and post- operative LSAT. All studies ranked as fair quality besides Esteller et al,10 which ranked as good quality. This is due to the study’s prospective design with consecutive recruitment of participants.
