Variables	Progression-free survival, HR (95% CI)	P value
BCL2 and MYC^a		0.004*
BCL2^low and MYC^low	1.0
BCL2^high and/or MYC^high	4.12 (1.56–10.88)
Body mass index, kg/m²		0.242
<27	1.0
≥27	1.81 (0.67–4.91)
NCCN-IPI^b risk		0.034*
Low or low-intermediate	1.0
High-intermediate or high	2.83 (1.08–7.37)

^a, MYC expression: low: positive stain in <40% of cells; high: positive stain in ≥40% of cells; ^a, BCL2 expression: low: positive stain in <50% of cells; high: positive stain in ≥50% of cells; ^b, NCCN-IPI: National Comprehensive Cancer Network International Prognostic Index. *,P value with significance. HR, hazard ratio; CI, confidence interval.
