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
Bladder cancer (BLCA) is the predominant type of urothelial carcinoma in urinary system, and resistance to cisplatin-based chemotherapy substantially worsens clinical outcomes, presenting a major therapeutic obstacle. In this study, we integrated genome-wide association study (GWAS) data with expression quantitative trait loci (eQTL) analyses, and applied Mendelian randomization (MR) to assess the causal effects of eQTLs from 19,942 genes on BLCA. By incorporating scRNA-seq data, our study also identifies differentially expressed genes (DEGs) in cisplatin-resistant BLCA cells and examined their causal associations with BLCA, aiming to elucidate genetic drivers of chemoresistance and tumor progression. Through this integrated approach, we identified the eQTL of the ARHGEF12 gene as a key mediator of cisplatin resistance. Bioinformatic analysis revealed that elevated ARHGEF12 expression was strongly associated with activation of the PI3K/Akt signaling pathway. To define ARHGEF12's role in cisplatin resistance, we established a cisplatin-resistant UM-UC-3/DDP model. Silencing ARHGEF12 markedly reduced chemoresistance, increased apoptotic cell death, and induced pronounced morphological changes. Pharmacological modulation with the ROCK inhibitor Y-27632 and a rescue assay with the Akt activator SC79 supported a model in which ARHGEF12 drives chemoresistance via RhoA/ROCK-dependent activation of the PI3K/AKT axis. This study is the first to integrate MR with single-cell transcriptomics to explore the genetic contribution to cisplatin resistance in BLCA. Our results uncover a novel mechanistic role of ARHGEF12 in BLCA progression and chemoresistance and suggest it as a potential therapeutic target for precision treatment strategies.
