Table 1 Median (95%CI) log10 reductions of CFU of Staphylococcus aureus on two types of needle-free connectors injection ports after 1, 3 and 7 days following two decontamination methods

From: An in vitro comparison of standard cleaning to a continuous passive disinfection cap for the decontamination of needle-free connectors
