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)
