No discernible differences were observed between B-cell and T-cell lymphomas in terms of endoscopic characteristics (P = 0.130), imaging characteristics such as thickening (P = 0.500), occupying (P = 0.549), or lymph node enlargement (P = 0.799), treatment strategy (P = 0.633), or laboratory indicators such as LDH (P = 0.797) and ADA (P = 0.136) (Supplementary Table S5). Here, ADA is linked to T-cell non-Hodgkin lymphoma.
