↵†Maximum sample size.
↵*P<0.1; mean serum ferritin concentration of females without inflammation (APP=0) in the 6.1- to 12-month postpartum/lactation period was slightly lower than mean serum ferritin concentration of those with mild (APP=1) inflammation.
a>b, P<0.05; mean serum ferritin concentration of females with mild inflammation (APP=1) in the 6.1- to 12-month postpartum/lactation period was higher than the concentrations in females in the other 3 subgroups.
