1 · What the graph read from it

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.

2 · The registry

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

This study characterized the sugar, organic acid, and phenolic profiles of 25 apple pulp samples from 12 cultivars to investigate their associations with antioxidant potential. Fructose and malic acid were the predominant free sugar and organic acid, respectively. Hierarchical clustering based on seven non-redundant chemical traits classified the samples into four distinct chemical types: acid-rich, sugar-enriched/low-phenolic, intermediate/low-accumulation, and phenolic-rich types. Phenolic-related traits showed stronger associations with in vitro antioxidant capacity than sugar- and acid-related traits. For cellular validation, polyphenol extracts from five representative samples were tested at 5 μg/mL, a concentration selected based on cell viability results under the tested conditions. The extracts significantly reduced H
