Table 2. Univariate Cox proportional hazards model to determine the association of OS with iSUV used as a continuous variable (iSUV data on 179 patients).

Variable HR (95 % CI) P-value
Age 0.993 (0.977, 1.01) 0.44
Length of tumor (cm) 1.07 (0.993, 1.14) 0.077
Baseline BMI 0.984 (0.952, 1.02) 0.35
iSUV (continuous) 1.02 (1, 1.04) 0.016

CI denotes confidence interval; BMI denotes body mass index; iSUV denotes initial standardized uptake value.
