Nonlinear associations Klotho and all-cause mortality, cardiovascular mortality among CKM stage 0–3 and stage 4 populations A: The relationship between Klotho and all-cause mortality among CKM stage 0–4 populations (fully adjusted RCS Model). B: The relationship between Klotho and cardiovascular mortality among CKM stage 0–4 populations (fully adjusted RCS Model). C: The relationship between Klotho and all-cause mortality among CKM stage 0–3 populations (fully adjusted RCS Model). D: The relationship between Klotho and cardiovascular mortality among CKM stage 0–3 populations (fully adjusted RCS Model). E: The relationship between Klotho and all-cause mortality among CKM stage 4 populations (fully adjusted RCS Model). F: The relationship between Klotho and cardiovascular mortality among CKM stage 4 populations (fully adjusted RCS Model). Adjustments in the model accounted for the following variables: age, gender, educational level, ethnicity, marital status, family PIR, smoking status, drinking status, BMI, diabetes, and hypertension
