  • Existence of cardiac diseases: existence of coronary artery disease and/or echocardiographic abnormalities.

  • *

    * Adjusted for age, sex, and duration of hemodialysis and existence of cardiac disease. The HR for each variable is expressed per increment of 1 unit of each variable. That for glycemic control group (A1C group) refers to good A1C group as 1, and that for sex refers to females as 1.
