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

Breviscapine, one of cardiovascular drugs extracted from a Chinese herb Erigeron breviscapinus, has been frequently used to treat cardiovascular diseases such as hypertension, angina pectoris, coronary heart disease and stroke. However, its poor water solubility and low bioavailability in vivo severely restrict the clinical application. To overcome these drawbacks, breviscapine solid dispersion tablets consisting of breviscapine, polyvinylpyrrolidone K30 (PVP K30), microcrystalline cellulose and crospovidone were appropriately prepared. In vitro dissolution profiles showed that breviscapine released percentage of solid dispersion tablets reached 90 %, whereas it was only 40 % for commercial breviscapine tablets. Comparative pharmacokinetic study between solid dispersion tablets and commercial products was investigated on the normal beagle dogs after oral administration. Results showed that the bioavailability of breviscapine was greatly increased by 3.45-fold for solid dispersion tablets. The greatly improved dissolution rate and bioavailability might be attributed to intermolecular hydrogen bonding reactions between PVP K30 and scutellarin. These findings suggest that our solid dispersion tablets can greatly improve the bioavailability as well as the dissolution rate of breviscapine.
