Figure 3. Hazard ratios for the primary end point stratified by median baseline serum creatinine level, estimated glomerular filtration rate (eGFR), and proteinuria.

Proteinuria denotes the urine protein–creatinine ratio. The P values for formal tests for treatment interaction were as follows: baseline serum creatinine level, P = 0.16; baseline eGFR, P = 0.09; and baseline proteinuria, P = 0.54.
