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

Oral cannabidiol (CBD) product use is increasing despite suboptimal pharmacokinetics (PK) of currently available formulations. This study aimed to investigate the PK of CBD formulated using the drug delivery technology DehydraTECH™, which is hypothesized to increase absorption by bypassing first-pass liver metabolism due to enhanced lipophilic composition. Anticonvulsant activity of the leading formulation was investigated in the maximal electroshock seizure (MES) model. For the PK studies, Sprague Dawley rats were orally administered 25 mg/kg CBD in MCT oil or test formulations incorporating DehydraTECH™ (n = 10 per group). Plasma, brain tissue and urine and feces samples were collected to determine comparative absorption, distribution, and excretion by liquid chromatography with tandem mass spectrometry (LC-MS/MS). For the efficacy studies, a series of experiments was conducted using the lead formulation (CBDtech) from the PK trial. Effective dose (ED) of CBDtech in comparison to Epidiolex® (50-100 mg/kg), time of peak efficacy (TPE), and median ED (ED50) were assessed in the acute MES model. Clinical observations, presence/absence of hind limb extension (HLE), and maximum seizure severity (MSS) were recorded. No abnormal clinical signs were observed following dosing in any study.
