Comparison between the two study periods (2006–2010 and 2013–2017) for CLABSI incidence densities (95% CI) per 1000 catheter days across BW categories (a) and VAP incidence densities (95% CI) per 1000 days of ventilation utilization across BW categories (b). P-values are obtained using Poisson Regression for testing whether incidence densities significantly differ between the two period for each BW category
