As illustrated in Figure 1 and Figure 2, urinary CD80 adjusted for urinary creatinine correlated negatively with baseline serum albumin in all patients, regardless of glomerulopathy (r = −0.5, p < 0.0001), whereas it correlated positively, albeit weakly, with baseline proteinuria (r = 0.31, p = 0.006). The gene discussed is CD80; the disease is lipoprotein glomerulopathy.
