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
Claudins (CLDNs) play a crucial role in regulating the permeability of epithelial barriers and can impact tumor behavior through alterations in their expression. However, the precise mechanisms underlying the involvement of CLDNs in breast cancer progression remain unclear. This study aimed to investigate the role of CLDN11 in breast cancer progression. Utilizing the TCGA database and clinical specimens from breast cancer patients, we observed reduced expression of CLDN11 in tumor tissues, which correlated with poor prognosis in breast cancer patients. In vitro, silencing of CLDN11 enhanced the proliferative and migratory characteristics of breast cancer cell lines MCF-7 and MDA-MB-231. Mechanistically, CLDN11 deficiency promoted the upregulation of Forkhead Box M1 (FOXM1) by activating the hedgehog signaling pathway, thereby sustaining tumor progression in breast cancer. In vivo, blockade of hedgehog signaling suppressed the tumor progression induced by CLDN11 silencing. Our study highlights the significance of the CLDN11/FOXM1 axis in breast cancer progression, suggesting CLDN11 as a potential diagnostic indicator and therapeutic target for clinical therapy.
