Kaplan-Meier survival curves for 40% eGFR decline divided based on median values of (A) recent thymic emigrant count, (B) proportion of recent thymic emigrants among CD4⁺ T cells, (C) proportion of CD28⁻ cells among CD4⁺ T cells, and (D) proportion of CD28⁻ cells among CD8⁺ T cells. High recent thymic emigrant count (RTEs) groups and High proportion of RTEs among CD4⁺ cells (RTE%) groups were significantly associated with a lower risk of ≥40% eGFR decline. RTEs, RTE%, the proportion of CD28⁻ cells among CD4⁺ T cells (CD28⁻/CD4⁺), and the proportion of CD28⁻ cells among CD8⁺ T cells (CD28⁻/CD8⁺) were divided into High and Low groups based on median values. Unadjusted hazard ratios (HRs) were calculated using Cox proportional hazards regression models
