Cultivar-Specific Quality and In Vitro Antioxidant Profiles of Pear Pastes.
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
Pear paste is a traditional Chinese product valued for its lung-moistening and antitussive effects. This study systematically evaluated the quality attributes and in vitro antioxidant profiles of pear pastes prepared in 2023 from 11 cultivars harvested in Henan Province, China. Multivariate analysis showed that genotype was the primary determinant of final product quality, with PC1 explaining 84.1% of the variance. Total phenolic content (TPC) ranged from 1052.8 to 1997.6 mg/kg, and total flavonoid content (TFC) from 478.1 to 1747.9 mg/kg across cultivars. Four cultivars displayed distinct advantages: 'Akizuki' (pronounced Maillard browning), 'Wanxiu' (highest free amino acids, 29.82 mg/g), 'Hongzaosu' (highest TPC, 1997.6 mg/kg; TFC, 1747.9 mg/kg; 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, 88.9 μmol TE/g), and 'Huangguan' (highest sensory score, 83.33; clarity, 87.65%). Antioxidant capacity was governed by a synergistic network of native phenolics, flavonoids, and Maillard reaction products, with the 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and ferric reducing antioxidant power (FRAP) assays recommended for consistent evaluation. These findings highlight the critical role of cultivar selection in tailoring the color, flavor, antioxidant activity, and overall quality of pear paste.
