α-Klotho is associated with cardiovascular and all-cause mortality in patients with stage 3b and 4 chronic kidney disease (CKD): a long-term prospective cohort study.

Background: α-Klotho deficiency may increase cardiovascular risks and worsen survival. We evaluated the association of α-Klotho with cardiovascular and all-cause mortality in pre-dialysis chronic kidney disease (CKD) patients.

Methods: In this prospective study, 75 non-diabetic CKD stage 3b-4 patients were followed-up for a median of 8 years.
