Phytochemical profiling and in vitro biological activities of Opuntia ficus-indica oil extracted by different methods.

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
Opuntia ficus-indica (L.) Mill., a prominent member of the Cactaceae, possesses notable economic, medicinal, and cosmetic relevance. This study characterizes the seed oil of O. ficus-indica, assessing its phytochemical profile, antioxidant capacity, and antimicrobial activity. Oil was extracted from seeds using three methods-Soxhlet, maceration, and ultrasound-assisted extraction and subjected to fatty acid profiling by gas chromatography-mass spectrometry (GC-MS). Approximately thirty bioactive compounds were identified, including fatty acids, carboxylic acids, aldehydes, and ketones. The physicochemical properties of each extract were determined (specific gravity, refractive index, acid value, peroxide value, and moisture content). Antioxidant activity was evaluated using ferric reducing antioxidant power (FRAP) and Ferric-bipyridine reducing capacity of total antioxidants (FBRC) assays, with results expressed as mg gallic acid equivalents (GAE) per g oil. Among the extracts, the maceration method yielded the strongest antioxidant performance (FBRC: 6.00 ± 0.15 mg GAE g
