Drought stress induces a biphasic NO accumulation in Arabidopsis thaliana.
Article in Plant signaling & behavior, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
We have recently reported the proteomic signature of the early (≤30 min) drought stress responses in Arabidopsis thaliana suspension cells challenged with PEG. We found an over-representation in the gene ontology categories "Ribosome" and "Oxidative stress along with an increased abundance of late embryogenesis abundant (LEA) and early response to dehydration (ERD) proteins. Since nitric oxide (NO) plays a pivotal role in plant responses to drought stress and induces LEA and DREB proteins, here we monitored the levels of NO in Arabidopsis cell suspensions and leaf disks challenged with PEG, and performed comparative analyses of the proteomics and transcriptomics data in public domain to search for a common set of early drought and NO responsive proteins. We show that under drought-stress, NO shows a biphasic time course, much like in response to ozone stress and that among the early drought and NO responsive proteins, the categories "DNA binding", "Nucleotide binding" and "Transcription regulator activity" are enriched. Taken together, present study suggests that in Arabidopsis the changing NO levels may play a critical role in early drought responsive processes and notably in the transcriptional and translational reprograming observed under drought stress.
