The relationship between serum α-Klotho with all-cause and cause-specific mortality.

Aims: The relationship between α-Klotho (αK) and mortality is controversial and has not been examined in a large, diverse cohort. We investigated the association between serum αK protein levels with all-cause and cause-specific mortality in a cohort representative of the US population.

Methods: We used National Health and Nutrition Examination Survey (NHANES) data from 2007 to 2016.
