The difference between the N values in the first and second columns is the number of participants who do not have data to calculate eGFRcr-cys, whereas the difference between the N in the second column and the sum of the N values in columns 3–6 is the number of participants who were missing a CKD risk category because of missing ACR data.
a
Mg albumin/g creatinine.
b
Total number of available participants at each time point.
c
Number of participants with sufficient data to calculate eGFRcr-cys.
d
Number of participants with sufficient data to assess CKD risk category using eGFRcr-cys and ACR.
