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
Abscisic acid-, stress- and ripening (ASR) -induced proteins are plant-specific proteins whose expression is up-regulated under abiotic stresses or during fruit ripening. In this study, we characterized an ASR protein from plantain to explore its physiological roles under osmotic stress. The expression pattern of MpAsr gene shows that MpAsr gene changed little at the mRNA level, while the MpASR protein accumulates under osmotic treatment. Through bioinformatic-based predictions, circular dichroism spectrometry, and proteolysis and heat-stability assays, we determined that the MpASR protein is an intrinsically unstructured protein in solution. We demonstrated that the hydrophilic MpASR protein could protect L: -lactate dehydrogenase (L: -LDH) from cold-induced aggregation. Furthermore, heterologous expression of MpAsr in Escherichia coli and Arabidopsis enhanced the tolerance of transformants to osmotic stress. Transgenic 35S::MpAsr Arabidopsis seeds had a higher germination frequency than wild-type seeds under unfavorable conditions. At the physiological level, 35S::MpAsr Arabidopsis showed increased soluble sugars and decreased cell membrane damage under osmotic stress. Thus, our results suggest that the MpASR protein may act as an osmoprotectant and water-retaining molecule to help cell adjustment to water deficit caused by osmotic stress.
