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
Gaoping Dahuangli is a landrace pear grown for more than four centuries in Gaoping County, Shanxi Province, and a National Geographical Indication (GI) product since 2013. What distinguishes it chemically from other pears-and how that distinction can be proved in the marketplace-has not been established. We profiled the fruit metabolome of Dahuangli and four commercial reference cultivars (Korla xiangli, Jingbaili, Clapp's Favorite, and Akizuki) by widely targeted UHPLC-MS/MS metabolomics (five varieties × three biological replicates, single harvest season) and measured eight quality attributes. Of 2335 annotated metabolic features, 136 were consistently more abundant in Dahuangli than in every reference variety. Flavonoids (48) and terpenoids (25) made up over half of this set; the single most enriched compound was sophorabioside, an isoflavone, at a minimum fold change of 120.7×. Dahuangli combined the firmest flesh (7.27 kg/cm
