Data are means±SD. P-values are for changes in morphometric measurements over 5 years. Abbreviations used: GBM, glomerular basement membrane; Sv(PGBM/glom), surface density of the peripheral glomerular basement membrane; Vv(Int/cortex), interstitial cortical fractional volume; Vv(Mes/glom), mesangial fractional volume per glomerulus; GlomV, mean glomerular volume; TFS/glom, total filtration surface per glomerulus.
