Within a same group (normo- or hyperglycemic), indicates statistical differences between colostrum and blood and # indicates differences between maternal blood and cord blood immunoglobulin levels. Indicates statistical differences in immunoglobulin levels between normo- and hyperglycemic women (in a row).
