In univariate analysis, serum albumin ≥35.0 g/L [OR: 3.0 (1.1–8.1), p = 0.026] and rituximab usage [OR: 3.6 (1.5–8.9), p = 0.003] were positively related to ORR, whereas HIV infection [OR: 0.3 (0.1–0.8), p = 0.012], CNS involvement [OR: 0.1 (0.0–0.8), p = 0.042] and gastrointestinal involvement [OR: 0.4 (0.2–1.0), p = 0.048] were negatively associated with ORR. Here, ALB is linked to HIV infectious disease.
