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 messagePtHSP17.8 was regulated by various abiotic stresses. Overexpression of PtHSP17.8 enhanced the tolerance to heat and salt stresses through maintain ROS homeostasis and cooperate with stress-related genes in Arabidopsis. Small heat shock proteins (sHSPs) play important roles in response to diverse biotic and abiotic stresses, especially in heat tolerance. However, limited information is available on the stress tolerance roles of sHSPs in woody species. To explore the function of sHSPs in poplar, we isolated and characterized PtHSP17.8 from Populus trichocarpa. Phylogenetic analysis and subcellular localization revealed that PtHSP17.8 was a cytosolic class I sHSP. The gene expression profile of PtHSP17.8 in various tissues showed that it was significantly accumulated in stem and root, which was consistent with the GUS expression pattern driven by promoter of PtHSP17.8. The expression of PtHSP17.8 could be induced by various abiotic stresses and significantly activated by heat stress. Overexpression of PtHSP17.8 enhanced the tolerance to heat and salt stresses in Arabidopsis. The seedling survival rate, root length, relative water content, antioxidative enzyme activities, proline, and soluble sugar content were increased in transgenic Arabidopsis under heat and salt stresses, but not in normal condition. The co-expression network of PtHSP17.8 were constructed and demonstrated many stress responsive genes included. The stress-related genes in the co-expression network were up-regulated in the PtHSP17.8 overexpression seedlings. These results suggest that PtHSP17.8 confers heat and salt tolerances in plants.
