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
Currently, the main types of roses circulating in China include Jinbian Rose, Kushui Rose and Pingyin Rose. Each type of rose has slight differences in usage and efficacy. There are many varieties of roses, and the quality of rose essential oils varies greatly. Almost no research has systematically studied the essential oils of various roses. In this experiment, three types of roses (Jinbian Rose, Kushui Rose, and Pingyin Rose) were selected as research subjects based on their efficacy and variety in the market. Essential oils were extracted from the three types of roses using hydrodistillation. Gas chromatography-mass spectrometry (GC-MS) was used to qualitatively analyze the volatile substances in the essential oils of different varieties of roses. The three types of rose essential oils were identified and differentiated using chemometric methods (including HCA, PCA, PLS-DA, and OPLS-DA). On the one hand, based on the GC-MS analysis results, 40, 48, and 40 volatile components were detected in Jinbian Rose, Kushui Rose, and Pingyin Rose, respectively. The chemical compositions were primarily dominated by macromolecular compounds such as long-chain alkanes, organic acids, and esters. On the other hand, eight markers with significant identification values were identified to distinguish among the three types of roses. In conclusion, based on GC-MS analysis and chemometric methods, this experiment distinguishes and identifies three types of roses from the perspective of essential oil components for developing an effective strategy for the identification of rose varieties.
