Correlation heatmap of OPN concentration and subsets of B cells and BAFF in infants and mothers. Pearson correlation with adjustment for multiple comparisons using the Benjamini-Hochberg method performed for each time point, presenting R values with P <0.05. Green color represents positive correlations and red color represents negative correlations. A OPN correlation heatmap for infants at birth, 2.5 months, 6 months, and 9 months. B OPN correlation heatmap for mothers at delivery and after 9 months
