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
Pleurotus pulmonarius is a medium temperature edible mushroom, and its yield and quality are severely affected by high temperature. However, the molecular mechanism of Pleurotus pulmonarius response to heat stress remains unknown. In this study, transcriptome sequencing and analysis of Pleurotus pulmonarius mycelia under heat stress were performed, related differentially expressed genes (DEGs) were verified by fluorescence quantitative PCR (qPCR) and the reduced glutathione content was detected. 5906 DEGs, including 1086 upregulated and 4820 downregulated, were identified by RNA-Seq. GO analysis revealed that DEGs were mainly enriched in the pathways of Aminoacyl-tRNA biosynthesis, pyrimidine metabolism, arginine and proline metabolism, fructose and mannose metabolism, and glutathione metabolism. qPCR analysis showed that the expression of ggt decreased after heat stress treatment, while gst2 and gst3 increased. The glutathione content in mycelia after heat stress was significantly higher than that in the control group. These results suggest that glutathione metabolism may play an important role in the response to heat stress. Our study will provide a molecular-level perspective on fungal response to heat stress and a basis for research on fungal environmental response and molecular breeding.
