  1. Linear Regression results are results from separate models for each independent variable
  2. Abbreviations: MAP Mean arterial blood pressure, eGFR Estimate glomerular filtration rate, M1 Mesangial hypercellularity>0.5, E1 Presence of endocapillary hypercellularity, S1 Presence of segmental glomerulosclerosis, T1 Tubular atrophy/ interstitial fibrosis 26–50% of cortical area, T2 Tubular atrophy/interstitial fibrosis≥50% of cortical area, C1 Crescents in at least one but < 25% of glomeruli, C2 Crescents in more than 25% of glomeruli
