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
objectivesPlant secondary metabolites include chemical compounds like flavonoids and phenolic acids. The use of these ingredients in traditional medicine to prevent or treat diabetes and cancer is becoming more prevalent because of their capacity to function as antioxidant agents. The objective of the research was to estimate the quantities of total phenols and flavonoids, together with the antioxidant capacity of various Dactylorhiza hatagirea extracts.
methodsTotal flavonoid and phenolic contents were determined by aluminum chloride and Folin-Ciocalteu techniques, respectively. 2,2-Diphenyl-1-picrylhydrazyl (DPPH) and 2,2- azino-bis (3-ethylbenzothiazoline-6-sulphuric acid (ABTS) approaches were used for assessing the scavenging of free radicals. Employing standard methods, the preliminary phytochemical activity of the extract was assessed, and its reducing power was tested in the presence of potassium hexacyanoferrate.
resultsA maximum concentration of 58.88 ± 0.32 of gallic acid was identified per gram of methanolic extract as phenolic content. Quercetin, at 85.51 ± 0.40 mg/gram, had the most flavonoid content. The strongest reducing power output measured was 1.968 ± 0.01 g. In comparison, the IC50 values for DPPH and ABTS assays were 162.79 ± 0.24 and 39.75 ± 0.20 μg/ml, respectively. Thus, this plant differs from others in that it has potent antioxidant capabilities.
conclusionThe methanolic crude extract of D. hatagirea and the estimated contents of phenols and flavonoids exhibited potent antioxidant action, particularly against DPPH and ABTS assays. Due to its relatively high phenolic and flavonoid contents, this plant is an exciting option for treating diseases. Therefore, secondary metabolites can be found and employed as low-resistance, multi-target antioxidant drugs for treating a variety of cancers, cardiovascular and neurodegenerative disorders, as well as other chronic diseases that are resistant to existing antibiotics. Our plant will be patented for its pharmacological applications.
