Young Children Display Diurnal Patterns of Salivary IgA and Alpha-Amylase Expression Which Are Independent of Food Intake and Demographic Factors

Figure 1

(a) The diurnal pattern of sAA and sIgA expression in toddlers on day one and day two. The morning and evening expression levels of sIgA (left) and sAA (right) on day one and day two are shown. The significant difference between morning and evening values is shown with for <0.05 and for <0.001. The p values were corrected for multiple testing. (b) Unusual diurnal pattern of sAA and sIgA in toddlers on day one and day two. The pattern of expression of sIgA (top panel) and sAA (lower panel) was selected and labelled unusual if it differed from general pattern for the whole population shown in (a). A significant difference between morning and evening calculated among the subgroup with unusual diurnal pattern is shown with for <0.05 and for <0.001. The p values were corrected for multiple testing.
