The nonlinear relationship between α-klotho and all-cause as well as cardiovascular mortality. (A-C) Nonlinear relationship analysis of α-klotho with all-cause mortality. (A)overall population; (B) females (C) males. (D-F) Nonlinear relationship analysis of α-klotho with cardiovascular mortality. (D)overall population; (E) females; (F) males. The red line represents the hazard ratio (HR) of α-klotho levels, the blue dashed line indicates the α-klotho values at different thresholds, and the shaded area represents the 95% confidence interval
