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
Polysaccharide derivatives are the most widely used chiral stationary phases (CSP) for the separation of chiral compounds. The availability of multiple adsorption and interaction sites of these CSPs is at the basis of their applicability; indeed, they are considered a quasi-universal SP, but concomitantly, this makes the full understanding of the separation process difficult. In this context, this study is intended to enhance our understanding of the influence of the backbone and substituent type of nine commercial polysaccharide-based CSPs on retention and selectivity of a set of 12 cannabinoids (including cannabichromene, cannabichromenic acid, cannabicyclol, and tetrahydrocannabinol enantiomers) under normal phase conditions. The application of statistical analysis to the results has highlighted a clear distinction between columns bearing electron-withdrawing and electron-donating groups, independent of the backbone. The obtained information are pivotal to fully exploit the potential of these differently substituted CSPs, as well as for the future design of novel chiral selectors.
