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 establish an in vivo-relevant Transwell dish-based dissolution test system for the "respirable" aerosols of inhaled corticosteroids (ICSs) using marketed inhaler products.

methods"Respirable" ≤ 5.8 or 6.5 μm aerosols of 7 ICSs from 11 inhaler products were collected onto the filter membranes under the modified assembly of the cascade impactor. Their dissolution in 10 ml of the simulated lung lining fluid (sLLF) was determined over time in the Transwell dish at 37°C and ~100% relative humidity in the presence of subsequent diffusive permeation across the Transwell's supporting membrane.

resultsWhile three ICSs with high-to-intermediate solubility enabled the first-order "sink" and complete dissolution in 6 h, 4 ICSs with poor solubility including fluticasone propionate (FP) resulted in the pseudo-zero-order "non-sink", slow and limited dissolution. The aerosol dissolution rate constants (k

conclusionsThe in vivo-relevant Transwell dish-based "respirable" aerosol dissolution test system was developed, kinetically discriminative in accordance with the ICS solubility, but indistinguishable for a given ICS between the marketed products.
