CTS: carpal tunnel syndrome; HCV: hepatitis C virus infection; MHD: maintenance hemodialysis; nPCR: normalized protein catabolic rate; Kt/Vurea (Daugirdes): dialysis clearance of urea; iPTH: intact parathyroid hormone; BLL: blood lead level; PM2.5: particulate matter with an aerodynamic diameter of <2.5 mm.
