[Retracted] Effect of Early Nutritional Assessment and Nutritional Support on Immune Function and Clinical Prognosis of Critically Ill Children

Figure 4

Comparison of C3 levels (). The horizontal axis from left to right represents before intervention and after intervention, and the vertical axis represents the C3 level (μmol/L). In the experimental group, the C3 levels before and after intervention were (1.55 ± 0.47) μmol/L and (0.39 ± 0.36) μmol/L, respectively. In the control group, the C3 levels before and after intervention were (1.52 ± 0.46) μmol/L and (0.76 ± 0.34) μmol/L respectively. The C3 levels of the experimental group before and after intervention were obviously different (t = 13.484, ). The C3 levels of the control group before and after intervention were obviously different (t = 8.913, ). The C3 levels of the two groups after intervention were obviously different (t = 5.419, ).
