Overall complications	1.68 (1.03 to 2.94)	NA	.04
Length of surgical stay	NA	18 (−3 to 44)	.09
Hospital costs	NA	7 (−5 to 23)	.26

^{^a}

Outcomes were examined in separate multivariable models, whereby the adjusted association of each outcome was modeled against hospital volume status while accounting for the effects of patient age, sex, race/ethnicity, comorbidities, and clinical pancreatic-related diagnosis, and the correlation of outcomes of patients who were treated at the same hospital.
