Normal Thymic Size and Low Rate of Infections in Human Donor Milk Fed HIV-Exposed Uninfected Infants from Birth to 18 Months of Age

Table 3

The term HIV-unexposed infants divided into the three feeding groups at 4 months of age: the number of infants, the thymic size (Ti, median, and range), and the weight and length (mean and range) at the times of assessment.
