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

Figure 2

Comparison of IgM levels (). The horizontal axis from left to right represents before intervention and after intervention, and the vertical axis represents the IgM level (μmol/L). In the experimental group, the IgM levels before and after intervention were (1.86 ± 0.76) μmol/L and (0.86 ± 0.44) μmol/L, respectively. In the control group, the IgM levels before and after intervention were (1.87 ± 0.74) μmol/L and (1.27 ± 0.53) μmol/L, respectively. The IgM levels of the experimental group before and after intervention were obviously different (t = 7.639, ). The IgM levels of the control group before and after intervention were obviously different (t = 4.422, ). The IgM levels of the two groups after intervention were obviously different (t = 3.993, ).
