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

backgroundEfficient delivery of aerosols to the lungs via the nasal route has been difficult to achieve, but it may offer benefits over the traditional oral route for a range of patient populations. Because slow, continuous delivery of short-acting agents could improve safety, tolerability, compliance, and efficacy when compared with the rapid, intermittent aerosol treatments delivered by mouthpiece or mask, a novel trans-nasal pulmonary aerosol delivery (tPAD) device was developed. The tPAD incorporates an aerosol particle-size selection chamber and a custom nasal cannula that are specifically optimized for aerosol delivery to the lung via the nasal route. The tPAD device produced a steady aerosol output (∼2 mL/h) from an optimized nasal cannula with negligible rainout in the cannula for up to 8 hours. The generated aerosol particles were small enough to minimize nasal deposition [volume median diameter (VMD) = 1.4 μm].

methodsIn this proof-of-concept study, gamma scintigraphy was used to quantitate deposition efficiency of

resultsThe tPAD device achieved high pulmonary deposition (39% ± 8%), based on emitted dose, and matched that of the oral jet nebulizer (36% ± 9%). Low fractions of aerosol deposition in the head and nose region were observed for tPAD (6% ± 6%) and jet nebulizer deliver (1% ± 1%) as well.

conclusionsA profile of high pulmonary deposition efficiency and low nasal dose may enable the sustained use of the tPAD platform with a variety of therapeutic agents for a range of pulmonary disorders.
