Histologic subtype of NHL as reported by reference pathology. For DL1, n = 39; for DL2, n = 71 (total, n = 110). For 2 patients further histologic subtyping was not available (aggressive lymphoma, not otherwise specified, n = 2). In 2 additional patients reference pathology review was not possible.
