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

backgroundAspirin is a nonsteroidal anti-inflammatory drug that is very effective in the treatment of inflammation and other health conditions, however, it causes gastric irritation. Recently, researchers have developed patents (US9757529, 2019) of inhalable aspirin for rapid absorption and circumvention of gastric irritation.

objectiveThe aim of this work was to formulate aspirin-loaded lipid based formulation in order to enhance oral bioavailability and inhibit gastric irritation.

methodsThis solid lipid microparticles loaded with aspirin (SLM) was formulated by a modified cold homogenization-solvent evaporation method. In vitro studies such as in vitro drug release, particle size, Encapsulation Efficiency (EE), micromeritic properties and loading capacity were carried out. Pharmacodynamics studies such as anti-inflammatory and ulcerative properties of the SLM were also carried out in Wistar rats.

resultsThe results showed that aspirin entrapped SLM exhibited the highest EE of 72% and particle size range of 7.60 + 0.141µm to 20.25 + 0.070µm. Formulations had about 55% drug release at 6h in simulated intestinal fluid pH 6.8. The formulations had good flowability that could facilitate filling into hard gelatin capsule shells. The SLM exhibited 100% gastroprotection against aspirin-induced ulcers (p < 0.05). The percentage of anti-inflammatory activities also showed that aspirin-entrapped SLM had 78% oedema inhibition at 7h, while the reference had 68% inhibition at 7h.

conclusionAspirin-entrapped SLM showed good sustained-release properties, enhanced antiinflammatory properties and total gastric protection from aspirin-induced ulcers and could be used as once-daily oral aspirin.
