Task: Answer Verification
Input (English): Question: Is fractional urinary excretion of IgG the most powerful predictor of renoprotection by ACE inhibitors in IgA nephropathy?
Answer: Renoprotection by ACEi is a multifactorial phenomenon: the best predictor of renoprotection is FEIgG, a marker of disruption of glomerular barrier to proteins; renoprotection depends not only on ability to reduce proteinuria, but probably also on antiinflammatory and antifibrotic activity.
Output (English): yes
