Along with the malnutrition severity, the serum transthyretin significantly decreased. However, no obvious changes were found in serum albumin. The mean value (Mean ± SD; 25.78 ± 4.09 cm) of mid arm circumference (MAC) was negatively correlated with MQSGA (r = -0.365; P = 0.002). Body mass index (BMI) (Mean ± SD; 21.6 ± 3.1 kg/m2) was also significantly negatively correlated with MQSGA (r = -0.392; P = 0.001). The areas under the receiver operating characteristic curve were 0.664 and 0.726, respectively.
