^aSurgical volume groups were identified based on quartile rank: 75^th percentile = very-high volume (>31.7cases/year); 51^st–75^th percentile = moderately-high volume (13.3–31.6 cases/year); 25^th–50^th percentile = intermediate volume (6.7–13.2 cases/year); and <25^th percentile = low volume (<6.7 cases/year)
