Univariate logistic regression analyses showed that HCV, HD duration, Kt/Vurea (Daugirdas), normalized catabolic rate (nPCR), Hb level, hypoalbuminemia (albumin <4 g/dL), log iPTH level, and BLLs were positively associated with CTS (Table 3). The gene discussed is GSTM1; the disease is Hypoalbuminemia.
