Hazard ratio for a low Tregs frequency

Variable	Univariate Cox regression		Multivariate Cox regression
	Hazard ratio (95 % CI)	p value	Hazard ratio (95 % CI)	p value
TNM stage	1.606 (1.133–2.276)	0.008	1.643 (1.144–2.361)	0.007
Tregs low	9.384 (1.173–75.093)	0.035	10.131 (1.256–81.719)	0.030

Univariate and multivariate Cox regression analyses for the TNM stage and a low number of Tregs on disease-specific survival are shown. The 95 % confidence interval (95 % CI) of the hazard ratio is indicated within parentheses
