Multivariate logistic regression of potential predictors of Hospital mortality.

Variables	OR (95 % CI)	p-value
Hospital mortality (reference: no)
HFpEF only	1.21 (0.90–1.62)	0.21
Lactate at presentation	1.10 (1.03–1.18)	0.004
Intubation first 24 h	2.53 (1.74–3.69)	<0.0001
Site of infection—lung	1.78 (1.36–2.34)	<0.0001

Variables included in the model were.

Imposed: HFpEF - (reference: no HFpEF and no HFrEF).

Stepwise: age; gender (reference: female); vital signs heart rate (HR); smoking; chronic kidney disease; hypertension; dyslipidemia; coronary artery disease; atrial fibrillation; diabetes mellitus; chronic obstructive pulmonary disease (COPD); lactate at presentation; procalcitonin; creatinine; phosphate; IV fluid first 6 h; IV fluid given in the first 24 h; norepinephrine given in the first 24 h; steroids given in the first 24 h; intubation first 24h; intubation in the first 48 h; site of infection (lung; urine; gastrointestinal system), urine bacteria; bacteria in wound—Enterococcus.

CI, confidence interval; h, hours; HFpEF, heart failure with preserved ejection fraction; HFrEF, heart failure with reduced ejection fraction; IV, intravenous; OR, odds ratio.
