Figure 2. Cows’ Milk Antibody Titers Over the First 9 Months of Life.
IgG (Panels A and B) and IgA (Panels C and D) class antibodies to cows’ milk (infant formula) in cord blood and at the ages of 3, 6, and 9 months in the casein hydrolysate group and control group. The bottom of the box plots indicate the 25th percentile and the top the 75th percentile. The circle symbols indicate the mean. The lower end of the whiskers represent the minimum observation and the upper end the maximum observation below the upper fence (1.5 interquartile range above the 75th percentile).
