Results are presented as N, n (%), median [IQR] or N normalized per 1000 line-days. Bold emphasis corresponds to the p-values which are statistically significant (i.e. p < 0.05)
CLABSI, central-line associated bloodstream infection
aP values corresponds to the chi-square test of independence and Kruskal–Wallis test, as appropriate
bP values correspond to ANOVA test of the increase in model fit by adding year to Poisson regression
