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
Gentamicin is a potent aminoglycoside antibiotic, but its clinical use is limited by severe nephrotoxicity. Experimental and transcriptomic studies have indicated that the extent of renal injury and recovery following gentamicin exposure may differ between sexes, yet the underlying molecular mechanisms remain poorly understood. In this study, we investigated sex-specific transcriptional signatures, hub genes, transcription factors, and druggable molecular pathways involved in gentamicin-induced kidney injury and recovery. RNA-seq data from rat kidney tissues (male, female, and combined groups) were obtained from the NCBI-GEO database and analyzed at two time points corresponding to injury (day 15) and recovery (day 29). Differentially expressed genes were identified and subjected to functional enrichment (GO/KEGG), hub gene, and transcription factor detection analyses, followed by drug-gene interaction screening using DGIdb. Males exhibited a broader but more homogeneous transcriptional response, whereas females showed a narrower yet more pronounced activation pattern. A conserved mitotic core (BIRC5, BUB1B, CCNA2, CDC20) was shared across sexes and phases. Sex-dependent divergence emerged primarily during the recovery phase: PBK, CCNB1, and NUF2 were identified as female-specific proliferative hubs, whereas CDCA8 was uniquely enriched in males. Transcription factors CENPA, FOXM1, and MYBL2 formed a shared regulatory backbone, while DNMT1 appeared predominantly in male injury samples, suggesting a male-biased epigenetic component. DGIdb integration showed that among sex-specific hub genes, only CCNB1 had druggable interactions, whereas PBK, NUF2, and CDCA8 lacked pharmacological matches. In contrast, several core cell-cycle regulators (BIRC5, BUB1B, BUB1, CCNA2, CDK1) were highly druggable. These findings demonstrate that gentamicin nephrotoxicity is governed by a shared cell-cycle core but modulated by sex-specific repair programs, providing a molecular basis for the development of sex-tailored therapeutic strategies.
