Univariate analysis of individual variables with regard to prostate cancer survival

	X 2	P-value
Gleason score	47	0.00
Pre-treatment PSA	102	0.00
TGFβ1	100	0.00
IL-7	26	0.04
IL-7receptor	102	0.00
Age	26	0.13

The variables IL-7 expression, IL-7 receptor expression, TGFβ1 expression and pre-treatment PSA levels were base 2 log-transformed before analysis. IL-7 interleukin 7, IL-7r = interleukin 7 receptor, TGFβ1 tumor growth factor beta 1, PSA prostate-specific antigen
