Table 4 Sensitivity analysis using distinct definitions of culture positivity to estimate the mortality risk
From: Culture positivity may correlate with long-term mortality in critically ill patients
Distinct definitions of culture positivity | Adjusted HR* (95% CI) |
|---|---|
Pathogens | |
At least one pathogen (main finding) | 1.27 (1.15–1.42) |
At least two pathogens | 1.40 (1.24–1.58) |
At least three pathogens | 1.52 (1.35–1.71) |
Culture sites | |
At least one site (main finding) | 1.29 (1.17–1.42) |
At least two sites | 1.44 (1.28–1.62) |
At least three sites | 1.67 (1.44–1.94) |
