Note: ACR = albumin-to-creatinine ratio, CI = confidence interval, eGFR = estimated glomerular filtration rate, HbA1c = glycated hemoglobin, PCR = protein-to-creatinine ratio.
↵* The % difference was calculated as the % frequency in the postintervention period minus the % frequency in the preintervention period.
↵† The difference in % change was calculated as follows: [(% frequency after screening in the intervention group — % frequency before screening in the intervention group) — (% frequency after screening in the control group — % frequency before screening in the control group)].
