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

Drought limits forage productivity and causes physiological dysfunction in plants. Melatonin (MT) can enhance stress tolerance, but the optimal dose and the mechanisms by which it mitigates drought-induced physiological and metabolic disturbances in Leymus chinensis remain unclear. A pot experiment under controlled soil moisture was conducted to screen the optimal MT dose for alleviating drought stress in L. chinensis seedlings and to elucidate the key physiological and metabolic mechanisms involved. Adding 100 μM MT significantly improved growth and photosynthetic performance under drought (p < 0.05). Specifically, DM100 increased plant height, root length, stem diameter, aboveground fresh weight (FW), aboveground dry weight (DW), and leaf relative water content (RWC) by 51.91%, 20.95%, 38.40%, 192.57%, 192.41% and 12.52%, respectively. Gas-exchange parameters were likewise enhanced (Gs: 183.38%, Tr: 270.37%, Pn: 114.24%), whereas intercellular CO₂ concentration (Ci) decreased by 113.34% (p < 0.05). Under drought, activities of antioxidant enzymes-superoxide dismutase (SOD), peroxidase (POD) and catalase (CAT)-were significantly elevated, and DM100 further increased these activities; conversely, drought-induced proline (Pro) accumulation was reduced by MT treatment. Untargeted metabolomics showed that drought markedly upregulated biosynthetic pathways for tryptophan, phenylalanine, phenylpropanoids and flavonoids. DM100 selectively attenuated excessive activation of tryptophan and phenylalanine metabolism, modulated phenylpropanoid/flavonoid responses, and coordinately regulated antioxidant and osmotic-adjustment metabolism. In summary, foliar MT at 100 μmol·L
