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
backgroundProstate cancer (PCa) is a leading cause of cancer-related mortality in men globally. While androgen deprivation therapy (ADT) can extend the asymptomatic phase and overall survival of patients with metastatic PCa, prolonged ADT often leads to the development of castration-resistant prostate cancer (CRPC) within 18-24 months. The mechanisms underlying CRPC remain incompletely understood, presenting a significant challenge in clinical prostate cancer treatment.
methodsIn this study, we investigated the role of Wnt5a, a member of the Wnt family, in CRPC. Tumor tissues from CRPC patients were analyzed to assess the expression levels of Wnt5a. Prostate cancer cells were used to examine the impact of Wnt5a on androgen-dependent and -independent growth, as well as sensitivity to bicalutamide. RNA-seq analysis, qRT-PCR, intracellular cholesterol content and the activation of the androgen receptor (AR) signaling pathway were evaluated to elucidate the mechanistic role of Wnt5a in CRPC progression. Drug target Mendelian randomization analysis was performed to investigate the effect of PCSK9 inhibitor on prostate cancer.
resultsOur study revealed a significant overexpression of Wnt5a in tissues from CRPC tumors. Wnt5a was found to enhance both androgen-dependent and -independent growth in prostate cancer cells while reducing their sensitivity to bicalutamide. Mechanistically, Wnt5a was shown to upregulate intracellular free cholesterol content and activate the AR signaling pathway, contributing to hormone therapy resistance in CRPC. PCSK9 inhibitor significantly reduced the risk of PCa.
conclusionsThe findings of this study highlight a novel molecular mechanism underlying endocrine therapy resistance in CRPC mediated by Wnt5a. Targeting Wnt5a or reducing cholesterol level would be a promising therapeutic strategy for the treatment of CRPC, providing new insights into potential avenues for combating this challenging form of prostate cancer.
