Fig. 2From: Carriage of antibiotic-resistant Gram-negative bacteria after discontinuation of selective decontamination of the digestive tract (SDD) or selective oropharyngeal decontamination (SOD)Time to first colonization with any Gram-negative bacteria resistant to tobramycin, ceftazidime, ciprofloxacin, meropenem or colistin in patients who were not already colonized with that specific resistant Gram-negative bacteria at time of ICU discharge. Bacteria that are intrinsically resistant to the antibiotics are excluded. Analysis after adjustment for individual ICU. p = 0.02 by Cox regression analysis for the difference between patients treated with selective decontamination of the digestive tract (dashed line; n = 426) or selective oropharyngeal decontamination (solid line; n = 409)Back to article page
