Nanoaerosols reduce required effective dose of liposomal levofloxacin against pulmonary murine Francisella tularensis subsp. novicida infection.

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
backgroundThe Institute of Theoretical and Experimental Biophysics in Moscow recently developed a new nanoaerosol generator. This study evaluated this novel technology, which has the potential to enhance therapeutic delivery, with the goal of using the generator to treat pulmonary Francisella tularensis subsp. novicida (F. novicida) infections in BALB/c mice.
resultsFirst, the analysis of quantum dots distribution in cryosections of murine lungs demonstrated that nanoaerosols penetrate the alveoli and spread more homogenously in the lungs than upon intranasal delivery. Second, the generator was used to aerosolize the antibiotic levofloxacin to determine the effectiveness of nanoaerosolized levofloxacin as treatment against F. novicida. The generator was capable of delivering a sufficient dose of nanoaerosolized liposome-encapsulated levofloxacin to rescue mice against 100LD50 of F. novicida.
conclusionsThe nanoaerosol-delivered dosage of liposome-encapsulated levofloxacin required to rescue mice is approximately 94× lower than the oral required dose and approximately 8× lower than the intraperitoneal dose required for rescue. In addition, treatment with nanoaerosols consumes less total volume of therapeutic solutions and is gentler on sprayed material than the aerosolization by a conventional three-jet Collison nebulizer as seen by the preservation of liposomes. This could represent a significant advance for the use of expensive therapeutics and lung directed therapies.
