Fold change in structural measures were statistically significantly associated with fold change in ACR. (A) GBM width, (B) Vv(Mes/glom), (C) Sv(PGBM/glom), (D) glomerular volume, and (E) percentage sclerosed glomeruli. For each figure, residuals were computed by regressing each of the variables on sex and baseline age, ACR, and the structural measure.
