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
The present study aimed to develop inhalable powder formulations with both dissolution enhancement and superior aerodynamic properties for potential pulmonary delivery of a poorly water-soluble drug, ivacaftor (IVA). The IVA-leucine (LEU) microparticle formulations were produced by spray drying and the physicochemical, aerosolization and cytotoxicity properties were characterized. Co-amorphous microparticle formulation was formed at the IVA: LEU 3:1 M ratio with hydrogen bond interactions as indicated by Fourier transform infrared spectroscopy (FTIR) results. Dissolution rate of the co-spray dried formulations was significantly improved as compared with the IVA alone or physical mixtures. The co-spray dried formulations exhibited > 80% fine particle fraction (FPF) and > 95% emitted dose percentage (ED) values respectively, with superior physical and aerosolization stability under 40℃ at 75% RH for 30 days. The laser scanning confocal microscopy results demonstrated that more IVA was uptake by Calu-3 cell lines for the co-spray dried formulation. In summary, our results demonstrated that co-spray drying IVA with LEU could achieve enhanced in vitro release and superior aerodynamic properties for pulmonary delivery of IVA.
