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
Jabuticaba (Plinia cauliflora), a Brazilian berry rich in phenolic compounds and anthocyanins, shows antioxidant and anti-inflammatory potential, but the instability and low bioavailability of these bioactive compounds limit their use, highlighting extraction and microencapsulation as preservation strategies. This study aimed to develop a spray-dried microencapsulated jabuticaba extract using maltodextrin as a carrier, while optimizing the extraction of phenolic compounds to enhance encapsulation efficiency and the retention of bioactive compounds. The peel and whole fruit were evaluated under different conditions (in natura, freeze-dried, oven-dried) to determine the most promising source of bioactive compounds. Extraction conditions included hydroethanolic solvents (50:50 and 80:20 v/v, acidified or non-acidified), solid concentrations (1%, 4%, and 15% w/v), and extraction times (2-24 h). The optimized extract was microencapsulated by spray drying using maltodextrin as the carrier. The freeze-dried peel showed higher phenolic recovery and antioxidant capacity than the whole fruit, with optimal extraction obtained using a 50:50 hydroethanolic solution and 2 h extraction. The extract showed high concentrations of phenolic compounds (62.38 ± 3.71 mg GAE/g), monomeric anthocyanins (11.63 ± 0.34 mg/g), and antioxidant capacity (DPPH: 14,017 ± 135 µmol Trolox/g); UPLC analysis identified cyanidin-3-glucoside (657.43 ± 2.93 mg/100 mL) and ellagic acid (71.17 ± 0.35 mg/100 mL) as the major phenolic compounds. The microencapsulated extract with maltodextrin presented low water activity (0.199 ± 0.014), spherical morphology, and retention of phenolic compounds. This study provides optimized extraction conditions and demonstrates the effectiveness of spray-drying microencapsulation using maltodextrin to stabilize jabuticaba phenolics, which may contribute to improving their stability and potential application as functional ingredients.
