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.
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
Rosa rugosa (R. rugosa), an economically important crop valued for its fragrance and medicinal properties, is highly susceptible to drought stress under open-field cultivation. However, the molecular mechanisms underlying its drought response remain largely unexplored. Here, we identified RrMYB2, a transcription factor that positively regulates drought tolerance in R. rugosa. Overexpressing RrMYB2 in Arabidopsis thaliana and R. rugosa enhanced drought tolerance. Virus-induced silencing of RrMYB2 plants exhibited impaired stomatal closure and reduced drought resistance. RNA-seq of silenced plants revealed that protein phosphatases type 2C (PP2C) genes, including RrHAB1, RrHAB2 and RrABI1, were significantly up-regulated. Biochemical analyses demonstrated that the negative regulation of PP2Cs by RrMYB2 was dependent on its interaction protein RrJMJ12, an H3K27me3 histone demethylase and genetic evidence indicated that RrJMJ12 acts downstream of RrMYB2 to negatively regulate drought resistance. Moreover, the RrMYB2-RrJMJ12 protein complex reduced RrJMJ12 binding to the CTCTGYTY motifs in the promoters of PP2C genes, with this inhibitory effect further enhanced under drought conditions. Collectively, our findings reveal a novel molecular mechanism in which a transcription factor cooperates with an epigenetic modifier to regulate drought tolerance in R. rugosa.
