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

backgroundHigh cadmium (Cd) stress causes phytotoxicity, inhibits plant growth, and alters gene expression and metabolite profiles. However, the molecular mechanisms underlying peanut responses to elevated Cd levels remain insufficiently understood.

resultIn this study, integrated transcriptomic and metabolomic analyses were conducted to investigate the responses of peanut roots to high Cd stress. Cd exposure significantly inhibited root growth and disrupted antioxidant enzyme systems in both roots and leaves. High Cd stress also altered ion uptake and transport in peanut plants. Transcriptome analysis identified 4,248 differentially expressed genes (DEGs), which were mainly associated with antioxidant enzymes, ion transport, and hormone-related processes. Metabolomic analysis identified 1,048 differentially expressed metabolites (DEMs). Under high Cd stress, the ABC transporter and plant hormone signal transduction pathways were significantly enriched. Key genes, including members of the ABCG subfamily, PP2C, and DELLA, showed differential expression and contributed to oxidative stress regulation. The response of peanut roots to Cd stress may involve coordinated changes in ion transport, antioxidant metabolism and hormone signal regulation.

conclusionThis study has proposed a multi-omics regulatory framework for the response of peanut roots to cadmium stress, providing potential candidate targets and theoretical basis for subsequent functional validation and research on cadmium tolerance-related mechanisms.
