Past history of stage I/II solid tumor malignancy impacts considerably on sepsis mortality: a propensity score matching analysis from the hellenic sepsis study group

Table 3 Forward step-wise Cox regression analysis of variables associated with 28-day mortality

Variable	Hazard ratio	95% confidence intervals	p-value
Septic shock	1.80	1.01–3.22	0.046
Acute kidney injury	2.06	1.21–3.49	0.007
History of coronary heart disease	0.36	0.14–0.89	0.028
History of stage I/II solid malignancy	1.79	1.13–2.85	0.014

Variables significantly different between survivors and non-survivors of Table 2 entered the equation as dependent variables. Variables remaining significant after four steps of analysis are shown
