Fig. 3From: Effect of chlorhexidine mouthrinse on prevention of microbial contamination during EBUS-TBNA: a randomized controlled trialRelative abundance of bacterial genera from needle wash samples. A total of 203 bacteria in the chlorhexidine mouthrinse group and 289 bacteria in the usual care group were identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. The dotted boxes represent the genera of oropharyngeal commensal bacteriaBack to article page
