When compared with patients with viral sepsis, patients with bacterial sepsis were older (p < 0.001), had higher PCT (p < 0.001), higher serum HNL (p < 0.001), higher CRP (p < 0.001) and higher leucocyte count (p < 0.004); they also had higher 7-day and 30-day mortality (p < 0.001) but no difference in the other measured outcomes. Here, CRP is linked to bacterial infectious disease with sepsis.
