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

Figure 1

Comparison of IgA levels (). The horizontal axis from left to right represents before intervention and after intervention, and the vertical axis represents the IgA level (μmol/L). In the experimental group, the IgA levels before and after intervention were (4.79 ± 0.93) μmol/L and (2.02 ± 0.91) μmol/L, respectively. In the control group, the IgA levels before and after intervention were (4.83 ± 0.89) μmol/L and (2.94 ± 0.88) μmol/L, respectively. The IgA levels of the experimental group before and after intervention were obviously different (t = 21.807, ). The IgA levels of the control group before and after intervention were obviously different (t = 16.070, ). The IgA levels of the two groups after intervention were obviously different (t = 9.886, ).
