  2. ORs are presented as unadjusteda and adjustedb for social class.
  3. ORs in bold indicate values that differ significantly from 1 (P<0.05).
  4. ORs in bold and underlined indicate values that differ significantly from 1 (P<0.01).
  5. aOR with only the implicit adjustment for the matching factors: sex, registration subdistrict and period of registration.
  6. bOR additionally adjusted for SES (based on ONS categories 1, 2, 3NM, 3M, 4, 5 defined by the father’s declared occupation at the time of the child’s birth).
