Table 5. Wilcoxon rank sum test to determine the association between iSUV (dichotomized by the median value [12.7]) and clinical parameters (n=179).

Covariate and iSUV	N	Mean +/- std, median (range)	P-value
Age
Low (<12.7)	89	66.3 +/- 10.2, 68 (30 - 84)	0.8336
High (>=12.7)	91	66.4 +/- 10.3, 68 (34 - 85)
Length of Tumor (cm)
Low (<12.7)	83	4.5 +/- 2.4, 4 (0 - 11)	0.0001
High (>=12.7)	89	6.1 +/- 2.3, 6 (2 - 13)
Baseline BMI
Low (<12.7)	89	27.9 +/- 6.3, 26.6 (19 - 63.9)	0.6725
High (>=12.7)	91	27.7 +/- 5.6, 27.6 (15 - 43.4)

iSUV denotes standardized unit value; std denotes standard; BMI denotes body mass index
