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

Soil salinization threatens agricultural development, and understanding the alkali tolerance mechanism of barley is crucial for breeding. Using the alkali-tolerant barley variety Jia-HY460-6R and the alkali-sensitive variety Noire Maroc as materials, morphological and physiological indicators were determined and proteomic analysis was conducted after treatment with 100 mmol·L⁻¹ Na2CO3:NaHCO3. The results showed thatJia-HY460-6R exhibited superior performance compared to Noire Maroc in terms of growth indicators, antioxidant capacity, ion balance, and osmotic regulation. A total of 1359 differentially abundant proteins were identified, and 27 key proteins were screened, involving multiple metabolic pathways such as the MAPK signaling pathway. This study provides a basis for understanding the molecular mechanism of barley alkali tolerance and breeding.
