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
Introduction: The FGFR3-TACC3 fusion gene exists in a variety of malignant tumors, including bladder cancer. In our ongoing research on the CRISPR-Cas13a gene-editing system, we reported the use of CRISPR-Cas13a gene-editing system to knockout FGFR3-TACC3 and inhibit the proliferation of bladder tumor cells. Purpose: This study aimed to use the CRISPR-Cas13a gene-editing system to target the FGFR3-TACC3 fusion gene in bladder cancer cells, which has the potential to be a new and effective treatment for bladder cancer. Materials and Methods: The efficacy of the CRISPR-Cas13a gene-editing system was analysed by qRT-PCR. The inhibitory effects of Cas13a-mediated knockdown of the FGFR3-TACC3 fusion gene on the proliferation of RT4 and RT112 cell lines were assessed utilizing CCK-8, EdU, and organoid formation assays. Subsequently, the comparative tumorigenic capability of RT4 cells with FGFR3-TACC3 knockdown achieved by Cas13a was examined in a nude mouse model. Results: At the cellular level, the comparative analysis of FGFR3-TACC3 knockdown efficacy between CRISPR-Cas13a and shRNA revealed a more pronounced reduction with the former. This knockdown effectively curtailed cellular proliferation, with CRISPR-Cas13a-mediated knockdown exhibiting a superior inhibitory effect over shRNA-mediated knockdown. In organoid cultures derived from RT4 cells, a similar trend was observed, with Cas13a-mediated knockdown of FGFR3-TACC3 leading to a more substantial suppression of proliferation compared to shRNA-mediated knockdown. In vivo tumor models corroborated these findings, demonstrating a significantly diminished tumor volume in the Cas13a-treated cohort relative to both the control and shRNA-treated groups. Conclusion: The CRISPR-Cas13a gene-editing system has been demonstrated to significantly suppress tumor proliferation both in vitro and in vivo, thereby presenting itself as a promising candidate for a novel and efficacious therapeutic intervention in bladder cancer treatment.
