Multivariate linear regression of potential predictors of LOS of the survivors in hospital.

Variables	β (95 % CI)	p-value
LOS
HFpEF only	−42.20 (−111.77; 27.37)	0.23
Vital signs HR(increase by 10 units)	−14.57 (−27.82; −1.31)	0.03
History of cancer	89.62 (23.90; 155.34)	0.008
IV fluid given in the first 24 h	21.37 (7.12; 35.63)	0.003

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; end–stage renal disease; TIA or stroke; vascular disease; history of cancer; coronary artery disease; atrial fibrillation; diabetes mellitus; 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 24 h; 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.
