Moreover, after adjusting for sex and age, history of cardiovascular disease, C-reactive protein, modified creatinine index, and geriatric nutritional risk index, lower psoas muscle gauge was independently associated with increased all-cause death and new cardiovascular events (adjusted hazard ratio (aHR) 7.65; 95% confidence interval (CI) 2.37–24.66 and aHR 2.98; 95% CI 1.54–5.75, respectively). The gene discussed is CRP; the disease is cardiovascular disorder.
