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
Dry powder inhalers (DPIs) have been proposed as an alternative administration route for protein and peptide drugs. However, DPI particles are easy to aggregate due to the strong interactions between the particles, leading to poor aerosolization performance. In this study, fragmented particles containing octreotide acetate (OA) were prepared by spray drying technique for dry powder inhalation, which were expected to decrease the particle-particle interaction by reducing the contact sites. Mannitol and ammonium carbonate were used as protein stabilizer and fragment-forming agent, respectively. The obtained fragmented particles presented larger particle size, lower density, better dispersibility, and well in vitro aerodynamic behavior (emitted dose > 97%, fine particle fraction ≈ 40%). The circular dichroism spectrum results indicated that OA maintained the stability throughout the spray drying process. The relative bioavailability of dry powder inhalation (DPI) compared with subcutaneous injection of commercial product was up to 88.0%, demonstrating the feasibility of DPI for OA delivery. These results confirmed that the proposed fragmented particles had great potential for pulmonary delivery of protein and peptide drugs in a painless, rapid, and convenient manner.
