ALB and acute kidney injury: This study showed that a higher urinary albumin to creatinine ratio (UACR) post-AKI was associated with an increased risk of kidney disease progression (hazard ratio 1.53 for each doubling; 95% CI, 1.45–1.62), and the urine albumin measurement was a strong discriminator for future kidney disease progression (C statistic, 0.82) [28].
