TABLE 2

Intrapersonal mean, SD, and coefficient of variation of serially measured A1C values are given compared with progression vs. nonprogression of renal status or a CVD event (coronary event, stroke, peripheral vascular event) during follow-up

  • Numbers of patients are given as nonprogressors/progressors. CV is given as percentage. P values are given for nonprogressors vs. progressors within a given group. CV, coefficient of variation; Normo, normal UAER; Micro, microalbuminuria; Macro, macroalbuminuria.
