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
C-REPEAT BINDING FACTORS (CBFs) are highly conserved plant transcription factors that promote cold tolerance. In Arabidopsis (Arabidopsis thaliana), three CBFs (CBF1 to CBF3) play a critical role in cold acclimation, and the expression of their corresponding genes is rapidly and transiently induced during this adaptive response. Cold induction of CBFs has been extensively studied and shown to be tightly controlled, yet the molecular mechanisms that restrict the expression of each CBF after their induction during cold acclimation are poorly understood. Here, we present genetic and molecular evidence that the decline in the induction of CBF3 during cold acclimation is epigenetically regulated through the Polycomb Repressive Complex (PRC) 2. We show that this complex promotes the deposition of the repressive mark H3K27me3 at the coding region of CBF3, silencing its expression. Our results indicate that the cold-inducible long noncoding RNA SVALKA is essential for this regulation by recruiting PRC2 to CBF3. These findings unveil a SVALKA-PRC2 regulatory module that ensures the precise timing of CBF3 induction during cold acclimation and the correct development of this adaptive response.
