a
A total of 1403 represents total enrollment between August 2003 and July 2017—protocol modifications (ie, addition of cancer type and patient-reported outcomes) result in smaller n values in these categories. All available data are included in each analysis set.
b
ASA status was collected as standard of care at one center. Data are presented for this single-center cohort of enrolled patients.
