Incident chronic kidney disease and newly developed complications related to renal dysfunction in an elderly population during 5 years: a community-based elderly population cohort study.

BACKGROUND: Few studies have evaluated the association between incident chronic kidney disease (CKD) and related complications, especially in elderly population.
