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

Anthocyanins are important flavonoid pigments responsible for coloration in maize kernels and are associated with nutritional and health-promoting properties. This study integrated metabolomic and transcriptomic analyses to investigate the biochemical and genetic basis of kernel pigmentation in three maize inbred lines with distinct kernel colors: yellow (Yellow-K), red (Red-K), and purple (Purple-K). Phenotypic and biochemical analyses revealed that anthocyanins accumulated exclusively in the pericarp of Red-K and in both pericarp and aleurone layers of Purple-K, with total anthocyanin content highest in Purple-K. Metabolomic profiling identified 1,845 differentially accumulated metabolites (DAMs) common across all comparisons, with flavonoids and anthocyanins significantly more abundant in colored kernels. Genotype-specific divergence in anthocyanin biosynthetic flux and decorative modifications showed that Purple-K specialized in malonylation and sambubiosylation, with massive accumulation of Pg3DiMalG; Red-K specialized in rutinosylation and 5-O-glycosylation. Transcriptome analysis identified differentially expressed genes (DEGs), of which 22 structural genes, including
