Abbreviations: aOR, adjusted odds ratio; OR, odds ratio; UPPP, uvulopalatopharyngoplasty.
a
Adjusted for age, sex, hospital level, diabetes, perioperative medication of an opioid, and index year of surgical procedure.
b
The other covariates were retained, but age was alternatively modeled as a restricted cubic spline with 4 knots.
