Observational studies reported in CKD populations that an elevated level of urinary uromodulin was associated with a reduced risk for a decline in eGFR and all‐cause mortality, showing an OR of 0.77 (95% CI 0.62–0.96) and 0.90 (95% CI 0.83–0.98), respectively.25 Here, UMOD is linked to chronic kidney disease.
