Ultrasound-Assisted Extraction of Antioxidant Polyphenols from Zheng'an White Tea: Process Optimization and Bioactivity.
Article in Foods (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
White tea is rich in polyphenols with antioxidant potential, but information on Zheng'an white tea remains limited. This study optimized water-based ultrasound-assisted extraction (UAE) using single-factor experiments and a Box-Behnken design and evaluated the antioxidant activity of the resulting extract. Tea-leaf microstructure, polyphenolic composition, and antioxidant capacity were assessed using scanning electron microscopy (SEM), liquid chromatography-mass spectrometry (LC-MS), in vitro radical-scavenging assays, and a
