  • Figures in brackets are number of patients: for the sensitivity, patients with good outcome among those achieving the target/total patients with good outcome; for the specificity, patients with poor outcome among those not achieving the target/total patients with poor outcome; for the PPV, patients with good outcome/target achievers; for the NPV, patients with poor outcome/target non-achievers. Of note, only 80 of the 90 patients had proteinuria values available at month 12.

  • hpf, high power field; NPV, negative predictive value; PPV, positive predictive value; RBC, red blood cells; sCr, serum creatine.
