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

rationaleΔ(9)-Tetrahydrocannabinol (THC) and cannabidiolic acid (CBDA) found in cannabis both reduce the distressing symptom of nausea, but their combined effects are not understood.

objectiveThe potential of combined doses of THC and CBDA to reduce acute nausea and anticipatory nausea in rodent models was assessed. MATERIALS AND

methodsFor acute nausea, the potential of cannabinoid pretreatment(s) to reduce LiCl-induced nausea paired with saccharin was evaluated in a subsequent drug free taste reactivity test, followed by a taste avoidance test. For anticipatory nausea, the potential of the cannabinoid pretreatment(s) to reduce the expression of LiCl-induced contextually elicited conditioned gaping was evaluated.

resultsCombined subthreshold doses of THC (0.01 and 0.1 mg/kg) and CBDA (0.01 and 0.1 μg/kg) reduced acute nausea. Higher doses of THC (1.0, 10 mg/kg) or CBDA (1.0, 10 μg/kg) alone, as well as these combined doses also reduced acute nausea. THC (10 mg/kg) interfered with conditioned taste avoidance, an effect attenuated by CBDA (10 μg/kg). On the other hand, combined subthreshold doses of THC (0.01 and 0.1 mg/kg) and CBDA (0.01 and 0.1 μg/kg) did not suppress contextually elicited conditioned gaping in a test for anticipatory nausea. However, higher doses of THC (1.0, 10 mg/kg) or CBDA (1.0, 10 μg/kg) alone, as well as these combined doses, also reduced anticipatory nausea. Only at the highest dose (10 mg/kg) did THC impair locomotor activity, but CBDA did not at any dose.

conclusionsCombined subthreshold doses of THC:CBDA are particularly effective as a treatment for acute nausea. At higher doses, CBDA may attenuate THC-induced interference with learning.
