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
Wild edible plants significantly contribute to the diets and nutrition of rural communities in many countries. Tetrastigma spp are well-known for their ethno medicinal, nutritional and culinary importance in the rural communities. It is important to put it under scientific investigation to provide deep understanding on the biochemical composition to reveal its importance in commercializing the fruits, open up new economic opportunities for smallholder farmers and rural communities by diversifying income sources and reducing reliance on a few major crops and also influence food crisis under circumstances. Thus, the present study aimed to investigate the nutritional properties, mineral content, and antioxidant activities of the pericarp of Tetrastigma leucostaphylum (Dennst.) Alston, an underutilized plant species. Pericarp analysis revealed high moisture content of 80.71%, with 0.096% fat, 1.20% protein, 12.50% carbohydrate, 1.15% ash, and 3.85% of fiber. Mineral analysis showed that pericarp contain significant amounts of essential minerals, among major elements, calcium being highest (42.53 mg/g) DW, nitrogen (10.03 mg/g DW), 9.03 mg/g DW of magnesium, and phosphorous (0.05 mg/g DW). Additionally, microelement iron found to be 1.01 µg/g DW. The study quantified anti-nutritional factors like phytate, and oxalate, 0.88 mg/g FW and 9.45 mg/g FW respectively. Phytochemical extraction was done using polar solvents revealing methanol as most effective solvent tested parameters. The methanol extract contains 7.12 mg GAE/g DW of total phenolics, 6.78 mg QE/g DW of flavonoids, and 0.78 mg BE/g DW of alkaloids. Among the antioxidant assays, DPPH assay showed highest activity in methanolic extract, with 17.13 mg AAE/g DW, followed by total antioxidant capacity at 13.55 mg AAE/g DW and FRAP at 7.56 mg AAE/g DW. In conclusion, the pericarp of Tetrastigma leucostaphylum fruit is rich in nutrients, essential minerals, and antioxidants, highlighting their potential as valuable food supplements.
