  1. aGeometric mean (± SD) adjusted for age, year of sampling, pre-pregnancy BMI, and weight change during pregnancy. Statistical analysis performed only on women born in Nordic countries. Results are shown only for organochlorine compounds that had adjusted means that were significantly different between groups with the lowest and highest consumption.
  2. bIncluding lean fish, fatty fish from the Baltic Sea and other fatty fish.
  3. cFatty fish originating from other areas than the Baltic Sea.
  4. *Significantly different from the group with lowest consumption, p ≤ 0.05.
