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
Background: Teratozoospermia, characterized by abnormal sperm morphology, is a major contributor to male infertility. Kinases, enzymes that catalyze the transfer of phosphate groups to proteins, are crucial regulators of cellular signaling pathways and play significant roles in sperm development and maturation. The purpose of the current study was to identify differentially expressed genes (DEGs) between teratozoospermia and normozoospermia samples and to investigate the role of kinases in these expression changes. Methods: An integrated analysis of transcriptome data was conducted from teratozoospermia and normozoospermia samples using publicly available gene expression omnibus (GEO) datasets. Three gene expression series (GSE) profiles of teratozoospermia from one superseries were selected and combined. Differential expression analysis was performed using the limma package in R, applying linear modeling and empirical Bayes statistics to identify DEGs with a threshold of adjusted p<0.05. A comprehensive list of human kinase genes was obtained from the KinHub database, and differentially expressed kinases between the two conditions were identified. Functional enrichment analyses including gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) pathways were conducted. Additionally, receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic potential of identified kinases. Results: Our analysis identified 1,292 DEGs. Among these, 34 kinases were identified (10 upregulated and 24 downregulated). ROR1 and STK39 showed the most significant changes. ROC analysis demonstrated strong diagnostic values for these kinases. Conclusion: This study is the first comprehensive analysis integrating transcriptomic data and kinase-focused gene expression profiling specifically in teratozoospermia, suggesting that kinase dysregulation may contribute to teratozoospermia and male infertility.
