Age (OR=1.094, P <0.001), female sex (OR= 3.44, P =0.005), diabetes (OR=3.756, P =0.008), and CRP (OR=1.09, P =0.015) were independent risk factors for sarcopenia, and serum magnesium (OR=0.755, p=0.042) and BMI (OR=0.701, P <0.001) were protective factors for sarcopenia in our study, as shown in Table 2. The gene discussed is CRP; the disease is diabetes mellitus.
