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 global oat harvest area occupied by China has been increasing annually. In this study, the fatty acid and triacylglycerol compositions, lipid concomitants, and antioxidant capacities of 16 oat oil cultivars in China were compared. All oat oils were found to be rich in unsaturated fatty acids (UFA), particularly oleic acid and linoleic acid. The main triacylglycerols in oat oil were first reported, including 1-palmitoyl-2-linoleoyl-3-oleyl-glycerol (PLO, 16.50-18.69%), 1,3-dioleoyl-2-linoleoyl-glycerol (OLO, 14.97-18.44%), and 1-palmitoyl-2,3-dioleoyl-glycerol (POO, 11.00-13.45%). Significant variations were observed among the cultivars in lipid concomitants, including tocochromanols (0-124.83 mg/kg), phytosterols (3380.94-5735.96 mg/kg), squalene (17.39-59.33 mg/kg), and polyphenols (255.47-513.99 mg GAE/kg). The antioxidant capacities of the different cultivars varied for DPPH (154.34-189.80 μmol VE/kg), ABTS (124.40-343.97 μmol VE/kg), and FRAP (834.32-2746.09 μmol VE/kg). Pearson correlation analysis showed a positive correlation between antioxidant capacity and the contents of polyphenols, squalene, and campesterol. Hierarchical cluster analysis classified the oat oils into distinct groups based on their phytosterol, polyphenol, monounsaturated fatty acids (MUFA), triacylglycerol, squalene, polyunsaturated fatty acid (PUFA), and tocochromanol contents. This study confirms that oat oil has potential as a functional oil and dietary supplement, and sheds light on the relationship between its nutritional quality and functionality, which may aid in the screening of beneficial oat oil cultivars.
