aBSI, bloodstream infection; MV, mechanical ventilation.
bp = 0.059 when compared to no BSI.
cp < 0.001 when compared to no BSI, and p = 0.053 when compared to microbiologically confirmed BSI.
dp < 0.005 when compared to microbiologically confirmed BSI and clinical sepsis.
ep = 0.097 when compared to microbiologically confirmed BSI.
