Cox proportional hazards models of PFS and OS on SUVmax and percent change in SUVmax from baseline

	PFS		OS
	HR (95% CI)	P	HR (95% CI)	P
Univariable Cox PH models
Baseline SUVmax	0.99 (0.97-1.02)	.55	0.99 (0.96-1.03)	.75
Cycle 2 SUVmax	1.08 (1.00-1.16)	.05	1.09 (0.99-1.20)	.06
Cycle 6 SUVmax	1.02 (0.90-1.14)	.79	1.06 (0.91-1.22)	.46
Δ2 = (baseline − cycle 2)/baseline × 100%	0.99 (0.97-1.00)	.02	0.98 (0.97-0.99)	.03
Multivariable Cox PH models (adjusting for IPI)
Baseline SUVmax	0.99 (0.96-1.01)	.30	0.99 (0.95-1.02)	.46
Cycle 2 SUVmax	1.06 (0.98-1.14)	.15	1.05 (0.96-1.16)	.30
Cycle 6 SUVmax	0.99 (0.88-1.13)	.96	1.03 (0.88-1.22)	.69
Δ2 = (baseline − cycle 2)/baseline × 100%	0.99 (0.97-1.00)	.03	0.99 (0.97-1.00)	.08
