Utilization of Guarana Agroindustrial Waste as a Source of Antimicrobial Compounds for Human Pathogenic Bacterial Removal in Wastewater Sample.
Article in Biotech (Basel (Switzerland)), 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
The guarana seed peel (GSP), an agroindustrial waste, was characterized for its chemical composition and evaluated for its antimicrobial activity as a potential source of antibacterial compounds for wastewater disinfection using UPLC-QTOF-MS analysis. UPLC-QTOF-MS analysis of GSP, its raw extract (GSPE), and its purified extract (GSPP) identified 36 compounds, including catechin and its oligomers: a B-type procyanidin dimer, pavetannin B6 (trimer), and cinnamtannin A2 (tetramer). Principal component analysis (PCA) separated GSPE from GSPP along PC2, and the purification step concentrated flavonoids-mainly catechin and its oligomers-in GSPP. Antimicrobial activity was assessed against the human pathogens
