Furthermore, patients with sarcopenia exhibited a greater prevalence of nutritional risk (NRS ≥ 3) and COPD, alongside lower serum albumin levels, higher total bilirubin, elevated serum creatinine, reduced triglycerides, increased C-reactive protein, and lower eGFR (all p values < 0.05). The gene discussed is CRP; the disease is chronic obstructive pulmonary disease.
