FIGURE 1:
Graphical depiction of the 12 primary definitions. All definitions are subsets of the KDOQI definition, which is shown in both panels for reference. The area of each circle is proportional to the sample size of patients defined as having clinically important MBD by that definition. The KDIGO definitions are not fully nested within the KDOQI definitions when only high values are considered, due to the different PTH target ranges.
