^aDeath due to bacteraemia episode occurred within 30 days from the day of positive blood culture.
^bSOFA score was registered 1–4 days after positive blood culture finding (median 3 days). Data available from 135 patients.
^cPlatelet count at least once lower than 50 10E⁹/L 0–8 days after positive blood culture
^dBilirubin level elevated (>25 μmol/L) at least once 0–8 days after positive blood culture
^eGlasgow coma scale lowered (<15) at least once 0–6 days after positive blood culture
^fHypotensive (MAP <70 mmhg) at least once 0–6 days after positive blood culture
