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

Δ(9)-Tetrahydrocannabinol (THC) discrimination in rodents is a behavioral assay that has been used to probe differences among classes of cannabinoids in rats. The purpose of this study was to determine whether traditional and anandamide-like cannabinoids were distinguishable in cannabinoid discrimination procedures in mice. Male mice were trained to discriminate 30 mg/kg THC or 70 mg/kg methanandamide from vehicle in a two-lever milk-reinforced drug discrimination procedure. After acquisition, agonist tests with THC, methanandamide, CP 55940, and anandamide were conducted, as were antagonism tests with rimonabant. Substitution (agonism) and antagonism tests were also carried out in female mice trained to discriminate THC. THC and CP 55940 fully substituted in THC-trained mice of both sexes. Further, THC substitution was rimonabant reversible. In contrast, mice injected with methanandamide or anandamide failed to respond substantially on the THC lever, even up to doses that decreased overall responding. In methanandamide-trained mice, methanandamide fully generalized to the methanandamide training dose. Rimonabant did not reverse this generalization. Although THC, CP 55940, and anandamide also increased responding on the methanandamide lever, the magnitude of substitution was less than for methanandamide. These results suggest incomplete overlap in the underlying mechanisms mediating endocannabinoid pharmacology and marijuana intoxication. Further, they suggest that methanandamide discrimination may involve a non-CB(1) receptor mechanism that is particularly prominent at higher doses.
