Our study highlights ABCC6 as a crucial factor in BLCA cisplatin resistance, with autophagy playing a significant role in this mechanism.

Kaplan-Meier curves and Cox proportional hazard models assessed death outcomes, with restricted cubic splines exploring non-linear relationships. Stratified and sensitivity analyses tested the robustness of results. The predictive performance of eGDR was compared with the Homeostasis Model Assessment of Insulin Resistance and triglyceride-glucose index for death outcomes. <b>Results:</b> 29,290 participants were included (median age: 53.00 years, 51.96% males), with 27,769 classified as having CKM. Higher eGDR was also associated with lower odds of progression to advanced CKM stages. In CKM patients, over a median follow-up of 8.92 years, 4,926 deaths occurred (17.7%), with 1,330 (4.8%) cardiovascular deaths and 3,596 (12.9%) non-cardiovascular deaths. Compared with the lowest eGDR quartile, CKM patients in the highest quartile had lower risk of all-cause death (HR=0.59, 95%CI: 0.52-0.66), cardiovascular death (HR=0.52, 95%CI: 0.41-0.66), and non-cardiovascular death (HR=0.60, 95%CI: 0.53-0.69) (all <i>P</i><0.001). Non-linear relationships between eGDR and death outcomes were observed (all <i>P for nonlinear</i><0.001). Subgroup and sensitivity analyses confirmed the robustness of these associations. Additionally, eGDR predicted death in CKM patients better than other IR markers. <b>Conclusions:</b> Our findings support the utility of eGDR as a risk stratification tool in CKM populations. Lower eGDR levels were associated with more advanced CKM stages and higher long-term mortality, suggesting its potential role in identifying high-risk individuals.</p>","PeriodicalId":14031,"journal":{"name":"International Journal of Medical Sciences","volume":"22 14","pages":"3779-3788"},"PeriodicalIF":3.2,"publicationDate":"2025-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12434822/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145075154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
