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.

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
Rice bran oil is one of oryzanol source oils. Oryzanol is an antioxidant compound that is related to the absorption of cholesterol, and is used in hyperlipidemia treatment and menopause problems. RBO extraction, purification and its γ-oryzanol content have been carefully reviewed. The quality and concentration of γ-oryzanol depend on the extraction process and purification. In selecting the extraction method to obtain the highest oryzanol content, in addition to comparing the concentration of oryzanol obtained and it can also be done by comparing the extraction kinetics parameters. Modeling according to physical or empirical kinetics can contribute in increasing the result of extraction. This study aims to determine the highest oryzanol content in rice bran oil, comparing several extraction methods and studies of rice bran oil extraction kinetic is necessary for scale up purposes. In this study is conducted Rice Bran Oil Extraction with n-Hexane solvent using several different methods, such as maceration, ultrasonication, and pneumatic press extractions. Independent variable that is used is the extraction time and yield as dependent variable. The study shows that the best extraction method to get the highest yield is 10.34 % by ultrasonicator and oryzanol content is 5.09 mg/g by a pneumatic press machine. According to kinetic parameter k
