Methods: Patients with liver cirrhosis (N = 210) were submitted to dual-energy x-ray absorptiometry (DXA). Appendicular muscle mass (AMM), AMM index (AMMI), upper limb muscle mass (ULMM), and ULMM index (ULMMI) were calculated. The Model for End-Stage Liver Disease, anthropometric measures, and the presence of ascites and edema were also registered. Multiple logistic regressions were performed to determine mortality predictors; the area under the receiver operating characteristic curve was used to establish the best cutoff point to predict mortality. Results: The mean follow-up duration was 49 & sect; 15.59 mo. ULMM and ULMMI were clearly associated with mortality (P = 0.007 and 0.001, respectively), whereas AMM and AMMI were not. After calculating the cutoff points for men and women, the presence of a depleted ULMMI as a categorical variable was associated with a mortality risk 2.5 times higher. Conclusions: The results suggest that using ULMMI is better than AMMI for predicting mortality of outpatients with cirrhosis, thus offering a better measure to detect muscle wasting in this population using DXA.
