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

backgroundMethyl jasmonate (MeJA) plays a key role in enhancing plant resistance to a wide range of diseases. However, the specific defense responses it induced and the underlying molecular mechanisms remain incompletely understood in many plant-pathogen systems. This study aimed to determine whether exogenous MeJA enhances resistance to leaf spot disease caused by Alternaria tenuissima in peony (Paeonia lactiflora) and to elucidate the associated molecular and biochemical mechanisms through integrated transcriptomic and biochemical analyses.

resultsCompared with the control (CK), pretreatment with 25-75 µmol L

conclusionsExogenous MeJA pretreatment enhances resistance to leaf spot disease caused by A. tenuissima in peony by promoting cell wall reinforcement and flavonoid accumulation. These findings highlight the potential of MeJA as a strategy for managing leaf spot disease in peony cultivation.
