Figure 2From: Micro-patterned surfaces reduce bacterial colonization and biofilm formation in vitro: Potential for enhancing endotracheal tube designsThe micro-patterned surface significantly reduces the colonization of the five microbial species most frequently associated with VAP when compared to un-patterned controls. All mean log reductions (across at least three experiments) are statistically significantly positive by single t-test *p < 0.05; **p ≤ 0.01. Error bars are the standard error of the mean log reduction.Back to article page
