A graph of the least-squares mean ratio of the change from baseline in the urinary albumin-to-creatinine ratio in the full analysis population.

In the CONFIDENCE trial in persons with chronic kidney disease and type 2 diabetes, combination therapy with finerenone and empagliflozin led to a greater reduction in the urinary albumin-to-creatinine ratio than either drug alone. Full trial results: nej.md/4jEVbbk
