Association of Intensity of Antipseudomonal Antibiotic Therapy With Risk of Treatment-Emergent Organisms in Children With Cystic Fibrosis and Newly Acquired Pseudomonas Aeruginosa.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhile Pseudomonas aeruginosa (Pa) eradication regimens have contributed to a decline in Pa prevalence in people with cystic fibrosis (CF), this antibiotic exposure might increase the risk of acquisition of drug-resistant organisms. This study evaluated the association between antipseudomonal antibiotic exposure intensity and acquisition risk of drug-resistant organisms among children with CF and new Pa infection.
methodsWe utilized data from the Early Pseudomonas Infection Control Clinical Trial (EPIC CT), a randomized controlled trial comparing Pa eradication strategies in children with CF and new Pa. The exposure was the number of weeks of oral or inhaled antipseudomonal antibiotics or ever versus never treatment with intravenous antipseudomonal antibiotics during the 18 months of EPIC CT participation. Primary outcomes were risks of acquisition of several respiratory organisms during 5 years of follow-up after EPIC CT estimated using Cox proportional hazards models separately for each specific organism.
resultsAmong 249 participants, there was no increased acquisition risk of any organism associated with greater inhaled antibiotic exposure. With each additional week of oral antibiotics, there was an increased hazard of Achromobacter xylosoxidans acquisition (HR, 1.24; 95% CI: 1.02-1.50; P = .03). Treatment with intravenous antibiotics was associated with an increased hazard of acquisition of multidrug-resistant Pa (HR, 2.47; 95% CI: 1.28-4.78; P = .01) and MRSA (HR, 1.57; 95% CI: 1.03-2.40; P = .04).
conclusionsResults from this study illustrate the importance of making careful antibiotic choices to balance the benefits of antibiotics in people with CF while minimizing risk of acquisition of drug-resistant organisms.
