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
Avocado landraces have gained great interest due to their importance in maintaining biodiversity and the presence of bioactive compounds in their fruit, depending on fruit tissues or ripening stages. This study aimed to evaluate the morpho-physicochemical and nutritional components of the peel, pulp, and seed tissues from Lagunero (LA) and Criollo (CA) avocado landraces at different ripening stages. Additionally, phenolic profiles were analyzed by using UPLC-DAD/ESI-MS, and a principal component analysis (PCA) was constructed to determine variations among the determined contents from avocado landraces, fruit tissues, and ripening stages. The CA showed a 30% higher fruit weight and higher percentages of seed (0.52%) and peel (3.62%) weight yields as compared to the LA. Ripening significantly affected the physical characteristics of LA and CA, and a substantial decrease in hardness (83%) after 4 days of storage. In LA, ripening resulted in an increase in fat content in both the peel and pulp. In contrast, CA showed an increase in protein content in the peel and pulp but a decrease in seeds; fat content increased significantly in the pulp of CA and carbohydrates remained the predominant component in all tissues, though they decreased slightly in CA peels during ripening. The ripe LA peel presented approximately 50% more total phenolic compounds than other tissues. The unripe CA peel showed a higher antioxidant capacity according to DPPH (3831.97 µMol Eq Trolox/g dw) and ABTS+ (3674.70 µMol Eq Trolox/g dw) assays. The main phenolic compounds identified in the avocado peel were chlorogenic acid, catechin, quercetin-3-O-hexoside, quercetin-3-O-pentoside, coumaric acid, caffeic acid, neochlorogenic acid, ferulic acid, kaempferol-3-O rhamnoside, and quercetin-3-O-rhamnoside. The PCA analysis revealed a strong correlation between chlorogenic acid and caffeic acid with TPC, while catechin was more closely related to antioxidant activity. These findings suggest that peel and seed tissues of avocado landraces, often considered byproducts, are valuable sources of bioactive compounds with high antioxidant potential.
