↵a The number of children in all exposure categories at each visit. Since the mother can change status from one visit to the next, some children will also alter status in the depression categories. CCP = the Danish childcare and vaccination programme. DiTe = diphtheria/tetanus/pertussis vaccination. MMR = measles, mumps, and rubella vaccination.
