  1. Data are presented as median (interquartile range) and n (%)
  2. Abbreviations: ACE-I angiotensin converting enzyme, ARB angiotensin receptor blocker, BP blood pressure, eGFR estimated glomerular filtration rate, UPCR urinary protein: creatinine ratio
  3. aThe patient with a UPCR < 4 g/g had decompensated nephrotic syndrome with refractory edema and an albumin nadir of 1.1 g/dL
  4. bNephrotic syndrome was defined as urinary protein: creatinine ratio > 3.5 g/g, serum albumin < 3 g/dL, and peripheral edema
  5. cOne patient in the second-line therapy group did not have baseline cholesterol or triglycerides
  6. dFailure of ACE-I or ARB was defined as a persistent UPCR > 4 g/g despite at least 6 months of therapy
