  1. mABP Mean Arterial Blood Pressure; Hb Haemoglobin; WBC White Blood Cell; UPCR Urine Protein Creatinine Ratio; eGFR estimated glomerular filtration rate; IgA Immunoglobulin A; IgG Immunoglobulin G; IgM Immunoglobulin M; C3 Complement factor 3; PLA2R phospholipase A-2 receptor
  2. The 24-hour value of proteinuria (g/24Hrs) is approximately 10-times the ratio of the UPCR in g/mmol creatinine
