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 present study investigated the phytochemical profiling, antioxidant, antimicrobial, hypoglycemic, and antiulcer activities of acetone, methanol, and petroleum ether extracts of aerial parts of Rumex hastatus. The antioxidant activity was examined through two techniques: the DPPH assay and the reducing power assay (RPA). The phytochemical constituents were studied by qualitative analysis (preliminary, GC-MS, HPLC) and quantitative analysis (spectrophotometry). The extracts were tested for hypoglycemic (anti-α-amylase) and antiulcer (anti-urease) activities through enzyme inhibition assays. To determine antimicrobial activity, a disk diffusion assay and a broth microdilution method were used. All the extracts were discovered to contain alkaloids, flavonoids, tannins, terpenoids, carbohydrates, and proteins. Saponins were only present in the methanol extract. HPLC analysis identified catechin, quercetin, gallic acid, and ascorbic acid in R. hastatus extracts. The findings revealed that the methanol extract exhibited the highest total flavonoid content (TFC) and total tannin content (TTC), and confirmed significant antioxidant activity in both DPPH and RPA assays. In addition, the methanol extract showed the greatest inhibition of both the enzymes α-amylase and urease as compared to the other extracts. All extracts showed potent antimicrobial activity against various tested microbes using both the disk diffusion method and the resazurin broth microdilution method.
