Results of the logistic regression model showing the effect of the INICC intervention on the central line-associated bloodstream infection rates.

Variables	Coeff (SE)	Adjusted OR* (95% CI)	P value
Period (intervention)	–0.636 (0.236)	0.53 (0.33–0.84)	0.007
CL-days†	0.034 (0.038)	1.03 (1.03–1.04)‡	0.000

CI, confidence interval; CL-days, number of central line days; Coeff, beta-coefficient of the logistic regression; OR, odds ratio; SE, standard error.

^*Adjusted OR for the logistic regression model including the two variables in the table.

^†CL-days: the total number of days of exposure to central line by all of the patients in the selected population during the selected time period.

^‡For a unit increase in the CL-days.
