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
Fuchs Endothelial Corneal Dystrophy (FECD) is an age-related disorder that affects about 4% of the population over the age of 40 years and is genetically associated with CTG repeat expansion in Transcription factor-4 (TCF4) gene. Although both genetic variants as well as environmental exposures like ultraviolent-A light (UVA) have been reported to cause FECD, there are no pharmacological treatments due to the lack of understanding of disease pathogenesis. To characterize the corneal endothelial (CE) cells in FECD individuals with or without CTG repeat expansions in TCF4, we performed RNA-sequencing (RNAseq) of three normal CE cell lines and seven FECD cell lines, including 3 generated from donors with TCF4 repeat expansions (FECD-R) and 4 from non-expanded donors (FECD-NR). Analysis of transcriptomic profiles in all 7 FECD cell lines compared to normal, revealed 214 differentially expressed genes or DEGs with 193 upregulated and 21 downregulated genes. Ingenuity Pathway Analysis (IPA) detected hepatic fibrosis and endothelial-mesenchymal transition pathways as top canonical pathways, which is consistent with extracellular matrix (ECM) deposition in the form of guttae seen in FECD. We identified and further validated transcriptional regulator genes like MAFB, TFAP2B, and POU6F2 to be differentially downregulated in FECD. Furthermore, 48 common DEGs were detected in both FECD-R and FECD-NR, and their upstream regulators included β-estradiol, TGF-β1, Aryl hydrocarbon receptor (AHR), and transcription regulators like CEBPA, CEBPB and SMARCA4. There were 29 genes identified to be differentially regulated only in FECD-R, compared to normal cells. In addition, other canonical pathways like tryptophan and melatonin degradation, Wnt signaling, AHR signaling, mitochondrial dysfunction, and estrogen receptor signaling were also highly enriched in FECD. Our findings support the previously proposed underlying mechanisms of disease progression, including role of transcriptional regulation of endothelial cells, mitochondrial dysfunction, Wnt- and estrogen receptor signaling, as well as the phenotypic clinical FECD hallmark of ECM deposits. Further investigation focusing on differentially expressed genes related to these pathways may be beneficial for elucidating disease-causing mechanisms and developing novel therapies for FECD.
