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
In prokaryotic and eukaryotic cells, the 3'-5'-exonucleolytic decay and processing of RNAs are essential for RNA metabolism. However, the understanding of the mechanism of 3'-5'-exonucleolytic decay in plants is very limited. Here, we report the characterization of an Arabidopsis (Arabidopsis thaliana) transfer DNA insertional mutant that shows severe growth defects in early seedling growth, including delayed germination and cotyledon expansion, thinner yellow/pale-green leaves, and a slower growth rate. High-efficiency thermal asymmetric interlaced polymerase chain reaction analysis showed that the insertional locus was in the sixth exon of AT4G27490, encoding a predicted 3'-5'-exonuclease, that contained a conserved RNase phosphorolytic domain with high similarity to RRP41, designated RRP41L. Interestingly, we detected highly accumulated messenger RNAs (mRNAs) that encode seed storage protein and abscisic acid (ABA) biosynthesis and signaling pathway-related protein during the early growth stage in rrp41l mutants. The mRNA decay kinetics analysis for seed storage proteins, 9-cis-epoxycarotenoid dioxygenases, and ABA INSENSITIVEs revealed that RRP41L catalyzed the decay of these mRNAs in the cytoplasm. Consistent with these results, the rrp41l mutant was more sensitive to ABA in germination and root growth than wild-type plants, whereas overexpression lines of RRP41L were more resistant to ABA in germination and root growth than wild-type plants. RRP41L was localized to both the cytoplasm and nucleus, and RRP41L was preferentially expressed in seedlings. Altogether, our results showed that RRP41L plays an important role in seed germination and early seedling growth by mediating specific cytoplasmic mRNA decay in Arabidopsis.
