Bonferroni correction was applied in AUC comparison to adjust for multiple testing. ACR, first-morning void albumin:creatinine ratio; AUC, area under the ROC curve; UAE, 24-hour urinary albumin excretion; UPE, 24-hour urinary protein excretion.
aP < 0.01 versus UAE.
bP < 0.01 versus UPE.
cP < 0.01 versus UAC.
