Correlation between GPX and serum MDA in protein energy malnutrition (P < 0.001) in Figure 4, correlation between GPX and serum protein carbonyl in protein energy malnutrition (P < 0.001) in Figure 5, correlation between SOD and serum protein carbonyl in protein energy malnutrition (P < 0.001) in Figure 6, correlation between SOD and serum MDA in protein energy malnutrition (P < 0.001) in Figure 7. The gene discussed is SOD1; the disease is protein-energy malnutrition.
