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 study targeted to compare the nutritional profile of two varieties of açaí, the white and purple, found in different mesoregions of Pará, Brazil. The research focused on analyzing levels of total phenolics, total anthocyanins, antioxidant capacity, and mineral composition in these two varieties. The study sought to identify significant differences between the two varieties in terms of nutritional composition and antioxidant potential, providing valuable information into the specific nutritional and functional properties of each type of açaí studied. Higher levels of total phenolics, total anthocyanins, and antioxidant capacity were observed in purple açaí fruits, with values of 806.17 ± 17.48 mgGAE/100 g, 81.73 ± 1.77 mg/100 g, and 19.25 ± 0.35 μmol of Trolox equivalent (TE)/g, respectively, compared to 401.92 ± 52.70 mgGAE/100 g, 37.70 ± 5.34 mg/100 g, and 6.17 ± 1.07 μmol TE/g in white açaí. HPLC-MS analysis identified and quantified monomeric anthocyanins in white açaí, using two distinct analytical methods, revealing average values of 0.29 and 1.05 μg/100 g for cyanidin-3-glucoside and between 0.74 and 3.13 μg/100 g for cyanidin-3-rutinoside, respectively, which were higher than those found in yellow tropical fruits. The quality of both purple and white açaí varied significantly among mesoregions, with fruits from floodplain soils demonstrating superior quality compared to those from sandy and solid soils in southeastern Pará. Mineral composition and microbiological characteristics were similar between white and purple açaí. These findings underscore the significant influence of mesoregion and soil type on açaí quality, emphasizing the superiority of fruits grown in floodplain soils.
