SERPINF1 and chronic kidney disease: When baseline serum creatinine or CKD stage was substituted for eGFR-EPI, elevated PEDF level remained a significant predictor of microalbuminuria/albuminuria progression (adjusted HR = 2.68; 95% CI = 1.00–7.20; P = .05; and HR = 3.19; 95% CI = 1.19–8.53; P = .021 for creatinine and CKD stage, respectively).
