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
MicroRNAs (miRNAs) are important molecules that regulate gene expression under salinity stress. Despite their evolutionary conservation, these regulatory elements have been shown to behave differently in different plant species under a particular environmental stress. In this study, we investigated the behavior of salt responsive osa-miR393a and its target gene (TIR1, LOC_Os05g05800) in salt-tolerant (FL478) and salt-sensitive (IR29) rice genotypes. It was found that the mature and precursor sequences of osa-miR393a as well as its cleavage site in TIR1 were conserved among salt tolerant and sensitive genotypes. Promoters of different salt-responsive miRNAs were also found to be less variable between salt-tolerant and salt-susceptible genotypes. Analysis of gene expression, promoter methylation, and cis-element abundance showed that osa-miR393a behaves differently in FL478 and IR29. Salt stress altered the expression pattern of osa-miR393a-TIR1 module in a time-dependent manner in the roots and shoots of two genotypes. Promoter methylation of this regulatory module was also altered at different time points under salt stress. Expression analysis in two genotypes indicated the overall down-regulation of osa-miR393a and up-regulation of TIR1 in FL478 and their reciprocal regulation in IR29. The expression results were complemented by the differential promoter methylation and cis-element abundance of this regulatory module. Together, the results of transcript abundance and promoter methylation of osa-miR393a-TIR1 module signified the association between these two processes which is reported for the first time in plants to the best of our knowledge.
