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
key messageCross-talk between light and ABA signaling is mediated by physical interaction between HY5 and ABI5 Arabidopsis. Plants undergo numerous transitions during their life-cycle and have developed a very complex network of signaling to integrate information from their surroundings to effectively survive in the ever-changing environment. Light signaling is one of the crucial factors that govern the plant growth and development from the very first step of that is from seedling germination to the flowering. Similarly, Abscisic acid (ABA) signaling transduces the signals from external unfavorable condition to the internal developmental pathways and is crucial for regulation of seed maturation, dormancy germination and early seedling development. These two fundamental factors coordinately regulate plant wellbeing, but the underlying molecular mechanisms that drive this regulation are poorly understood. Here, we identified that two bZIP transcription factors, ELONGATED HYPOCOTYLE 5 (HY5), a positive regulator of light signaling and ABA-INSENSITIVE 5 (ABI5), a positive regulator of ABA signaling interacts and integrates the two pathways together. Our phenotypic data suggest that ABI5 may act as a negative regulator during photomorphogenesis in contrast, HY5 acts as a positive regulator of ABA signaling in an ABA dependent manner. We further showed that over-expression of HY5 leads to ABA-hypersensitive phenotype and late flowering phenotype. Taken together, our data provides key insights regarding the mechanism of interaction between ABI5-HY5 that fine tunes the stress and developmental response in Arabidopsis.
