Patient populations are as follows: all, N = 689; CHOP-21, n = 178; CHOP-14, n = 172; CHOEP-21, n = 170; and CHOEP-14, n = 169. NK indicates natural killer; and NOS, not otherwise specified.
Diagnosis of aggressive B- or T-cell lymphoma was confirmed upon pathology review; however, due to quality of quantity of the biopsy material, a further subclassification was not possible.
