Açai Berry (Euterpe oleracea) Dietary Supplements: Variations in Anthocyanin and Flavonoid Concentrations, Phenolic Contents, and Antioxidant Properties.
Article in Plant foods for human nutrition (Dordrecht, Netherlands), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
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
Açai (Euterpe oleracea) is a palm plant that is native to South America and produces deep purple berry fruits. Despite açai's popularity as a dietary supplement, little is known about the phenolic composition and antioxidant properties of commercially available açai berry products. Therefore, twenty açai supplements in a variety of forms (e.g., capsule, powder, frozen pulp, and liquid) were analyzed for their total phenolic and anthocyanin contents, individual anthocyanin and other flavonoid concentrations, and antioxidant capacities. Hierarchical cluster analysis was then used to group açai supplements into categories based on similarities in their chemical profiles and antioxidant properties. Results showed that over half of the supplements contained little or no açai fruit or had sufficient amounts of water to substantially lower the concentration of açai chemical components. Additionally, two açai supplements contained unlisted ingredients that greatly altered the products' chemical properties. Chromatographic analysis of individual anthocyanins and other flavonoids was useful in identifying the presence of açai fruit within the dietary supplements while complimentary in vitro spectroscopic assays aided in detection of adulterants. This study highlights the complexity of the dietary supplement market while also showing the importance of collectively analyzing data from multiple complimentary techniques when evaluating açai berry products.
