Title | Change From Baseline in Estimated Glomerular Filtration Rate by the Cockcroft-Gault Formula (eGFRcg) in Participants With Moderate or Severe Renal Impairment and Hepatically Impaired Participants at Week 24 |
---|---|
Description | GFR is a measure of the rate at which blood is filtered by the kidney. Cockcroft-Gault is an equation (calculation) used to estimate GFR based on serum creatinine, weight, and gender. eGFRcg = (140 - age in years) x (body weight in kg) x (0.85 if female) divided by 72 x serum creatinine in mg/dL. Moderate renal impairment= 30 mL/min ≤ eGFRCG ≤ 59 mL/min Severe renal impairment= 15 mL/min ≤ eGFRCG < 30 mL/min Change from baseline was calculated as the value at Week 24 minus the value at Baseline. |

Title | Change From Baseline in eGFRcg in Participants With Moderate or Severe Renal Impairment and Hepatically Impaired Participants at Week 96 |
---|---|
Description | GFR is a measure of the rate at which blood is filtered by the kidney. Cockcroft-Gault is an equation (calculation) used to estimate GFR based on serum creatinine, weight, and gender. eGFRcg = (140 - age in years) x (body weight in kg) x (0.85 if female) divided by 72 x serum creatinine in mg/dL. Moderate renal impairment= 30 mL/min ≤ eGFRCG ≤ 59 mL/min Severe renal impairment= 15 mL/min ≤ eGFRCG < 30 mL/min Change from baseline was calculated as the value at Week 96 minus the value at Baseline. |
