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

Enabling formulations based on hydroxypropyl-β-cyclodextrins (HPβCD), micellar preparation, and liposomes have been designed to deliver the racemic mixture of a lipophilic cannabinoid type 2 agonist, MDA7. The antiallodynic effects of MDA7 formulated in these three different systems were compared after intravenous (i.v.) administration in rats. Stoichiometry of the inclusion complex formed by MDA7 in HPβCD was determined by continuous variation plot, electrospray ionization-mass spectrometry (ESI-MS) analysis, phase solubility, and nuclear magnetic resonance studies and indicate formation of exclusively 1:1 adduct. Morphology and particle sizes determined by dynamic light scattering and transmission electron microscopy show the presence of a homogeneous population of closed round-shaped oligolamellar MDA7 containing liposomes, with an average size of 118 nm [polydispersity index (PDI) 0.03]. Monodisperse micelles exhibited an average size of 14 nm (PDI 0.09). HPβCD-based formulation administrated in vivo was composed of two discrete particles populations with a narrow size distribution of 3 nm (PDI 0.04) and 510 nm (PDI 0.02). HPβCD-based formulation dramatically improved antiallodynic effect of MDA7 in comparison with the liposomes preparation. Through inclusion complexation and possibly formation of aggregates, HPβCD can enhance the aqueous solubility of lipophilic drugs, thereby improving their bioavailability for i.v. administration.
