ALB and chronic kidney disease: Tangri et al. developed a model to predict progression of CKD that was validated in thirty-one cohorts, including 721,357 participants with CKD stages 3 to 5 (including age, gender, eGFR, albuminuria, serum calcium, serum phosphate, serum bicarbonate, and serum albumin) with a good performance of overall C-statistics (0.90; 95% CI 0.89–0.92).
