The effect of provenance and species on the chemical composition of
Article in Pharmaceutical biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCommercial herbal teas marketed as
objectiveTo evaluate the chemical equivalence of commercial MATERIALS AND
methodsSixteen commercial tea samples labeled as
resultsSignificant qualitative and quantitative heterogeneity was observed across all samples, including those labeled as the same species. Oenothein B was the dominant compound but exhibited high variability (7.9-48.7 mg/g DW; CV >50%) and was significantly higher in DISCUSSION: Oenothein B, hyperoside, and isoquercitrin were identified as priority quality markers based on abundance and analytical suitability. Structural reassessment demonstrated that pharmacological ranking alone may be misleading for polyphenol-rich matrices due to redox-related interference.
