Table 3 Comparison of survival difference between patients with culture-positive and culture-negative sepsis

From: Comparing mortality between positive and negative blood culture results: an inverse probability of treatment weighting analysis of a multicenter cohort

  Subgroups Crude OR
Culture positive vs culture negative
IPTW-adjusted OR
Culture positive vs culture negative
Early mortality Full cohort 1.07 (0.64,1.80) 0.95 (0.56,1.62)
SIRS 1.02 (0.13,8.23) 1.18 (0.19,7.31)
Severe sepsis and septic shock 0.90 (0.521.53) 0.83 (0.47,1.44)
Severe sepsis and septic shock, excluding Staphylococcal bacteremia 1.19 (0.65,2.19) 1.21 (0.65,2.26)
Late mortality Full cohort 2.95 (1.81,4.79)*** 1.95 (1.14,3.32)*
