In all cases, univariate analysis identified nine factors to be significantly associated with the presence of sarcopenia: age (P < 0.0001), body mass index, (BMI, P < 0.0001), presence of LC (P = 0.0416), total bilirubin (P = 0.0276), serum albumin (P = 0.0008), alkaline phosphatase (ALP, P = 0.0143), estimated glomerular filtration rate (eGFR, P = 0.0178), serum sodium (P = 0.0164), and our classification of serum zinc concentration (P = 0.0009) (Table 2). The gene discussed is ALB; the disease is sarcopenia.
