Partial regression residual plot of the associations between tumor necrosis factor receptors (TNFRs), percent of normal endothelial cell fenestration (ECF), and mesangial fractional volume (VvMes). The residuals were computed from regressing each of the following variables: age, sex, diabetes duration, hemoglobin A1c, body mass index, and mean arterial pressure. Exclusion of the single outlier did not change the significance of associations between 2 morphometric variables. Reprinted with permission from Pavkov ME, Weil EJ, Fufaa GD, et al.
