  • a HR associated with a 33% increase in the proportion of values satisfying KDOQI guidelines. For example, the same hazard would apply for an increase from 0 to 1, from 1 to 2, or from 2 to 3 values within guidelines.

  • b HR associated with 100% of values satisfying KDOQI guidelines.

  • c HR associated with a 33% increase in proportion of values satisfying KDOQI guidelines. For example, the same hazard would apply for an increase from 0 to 4, from 4 to 8, or from 8 to 12 values within guidelines.
