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

purposeTo improve the quality of aerosol delivery to infants, the iDP-ADS was advanced to include dual-prong nose-to-lung aerosol administration with a bifurcating interface, consistently monitor lung pressures and control ventilatory parameters with a pressure monitoring and control (PMC) unit, and implement flexible nasal prongs for use across a range of subject sizes.

methodsFour bifurcating flow pathways were integrated into the iDP-ADS and tested in vitro with a full-term infant nose-throat (NT) model for comparison to the performance of a single-prong interface. After selecting the best-performing flow pathway, flexible prong designs were evaluated in the same model and chosen for additional testing. Realistic pulmonary mechanics (PM) and age-appropriate tidal volumes were used to simulate ventilation with the PMC unit and aerosol delivery in full-term and 34-week gestational age preterm NT models.

resultsThree of the four bifurcating flow pathways matched the performance of the single-prong design (tracheal filter delivery of ~55%), and the FP4 design with co-flow was selected. A flexible prong version of FP4 produced similar performance to the rigid version. Measurements from the PMC unit demonstrated that consistent air volumes under safe operating pressures could be delivered with a PEEP between 4-6 cmH

conclusionsThe best-performing interface with flexible prongs matched the lung delivery efficiency of a high-transmission single-prong interface and delivered high aerosol doses through late-preterm to full-term NT models.
