Similarly, MCH was significantly higher in neonate COVID-19-positive patients (32.7 g/dL, IQR; 30.8–34.6) and significantly lower in COVID-19-positive infants (26.8 g/dL, IQR; 25.7–27.9) and children (27.5 g/dL, IQR; 26–28.7) compared to COVID-19-negative patients of the same age group (28.5 g/dL, IQR; 26.7–30.1, 28.6 g/dL, IQR; 26.4–30.1, and 28.3 g/dL, IQR; 26.3–29.8, respectively) (p-values of <0.001, <0.001, and <0.01, respectively). Here, PMCH is linked to COVID-19.
