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.
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
The effect of quantitative structural properties of drugs on the extent of lymphatic transport is not well understood. Our study aimed to describe these principles in four cannabinoids, cannabidiol (CBD), cannabigerol (CBG), cannabichromene (CBC), and cannabinol (CBN) administered as oil solutions and nanoemulsions. A series of studies in jugular vein cannulated rats and anesthetized mesenteric lymph duct cannulated rats was conducted to measure drug oral bioavailability and lymphatic transport. Log P was measured, and quantitative structural properties were correlated to the extent of lymphatic absorption. Nanoemulsion did not increase the absolute bioavailability via lymph in CBD but led to an 8-fold increase in CBG and a 3-fold increase in CBC and CBN. There was an even higher increase in the absolute bioavailability via portal vein (11-fold for CBD, 71-fold for CBG, 8-fold for CBC, and 13-fold for CBN). Relative bioavailability via lymph increased with decreasing smallest orthogonal molecular size and topological polar surface area. Nanoemulsion did not affect the total oral bioavailability but led to an increased absorption into portal blood. Intestinal lymphatic transport plays a major role in the absorption of CBD, CBG, CBC, and CBN. Planarity of the molecule and low surface polarity could be crucial structural features facilitating lymphatic transport.
