Distribution of angiogenic biomarkers by mortality, bacteremia, and combined outcomes. Circulating levels of Ang-2, sICAM-1 and the Ang-2:1 ratio at admission were associated with increased risk of death and the combined outcome of death and bacteremia. Only the Ang-2:1 ratio was significantly associated with bacteremia. Ang-1 levels at admission were not associated with any of the clinical outcomes. * indicates p < 0.05 based on conditional logistic regression adjusting for relevant confounding variables: sex and lethargy for mortality outcome, sex for bacteremia outcome, and sex, lethargy and temperature for combined case outcome
