1 · What the graph read from it

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.

2 · The registry

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

Nebulization is currently used for delivery of antibiotics for respiratory infections. Bacteriophages (or phages) are effective predators of pathogens including Pseudomonas aeruginosa commonly found in the lungs of patients with cystic fibrosis (CF). It is known that phages and antibiotics can potentially show synergistic antimicrobial effect on bacterial killing. In the present study, we investigated synergistic antimicrobial effect of phage PEV20 with five different antibiotics against three P. aeruginosa strains isolated from sputum of CF patients. The antibiotics included ciprofloxacin, tobramycin, colistin, aztreonam and amikacin, which are approved by U.S Food and Drug Administration (FDA) for inhaled administration. Phage and antibiotic synergy was determined by assessing bacterial killing performing time-kill studies. Among the different phage-antibiotic combinations, PEV20 and ciprofloxacin exhibited the most synergistic effect. Two phage-ciprofloxacin combinations, containing 1/4 and 1/2 of the minimum inhibitory concentration (MIC) of ciprofloxacin against P. aeruginosa strains FADD1-PA001 (A) and JIP865, respectively were aerosolized using both air-jet and vibrating mesh nebulizers and the synergistic antibacterial activity was maintained after nebulization. Air-jet nebulizer generated droplets with smaller volume median diameters (3.6-3.7 µm) and slightly larger span (2.3-2.4) than vibrating mesh nebulizers (5.1-5.3 µm; 2.1-2.2), achieving a higher fine particle fraction (FPF) of 70%. In conclusion, nebulized phage PEV20 and ciprofloxacin combination shows promising antimicrobial and aerosol characteristics for potential treatment of respiratory tract infections caused by drug-resistant P. aeruginosa.
