The variance of the random effect among the 26 areas was highly significant ( p < 0.001) for all included health outcomes (see Table 1 ).

A possible trend toward reduced FA-effect at the end of the study period should motivate a more thorough study of whether the effects are retained in later years, examining the mediators and moderators of importance for achieving an maintaining the effects that FA services seem to have the potential to create on maternal and fetal health across pregnancy and birth.
The lower rates using the 2.5 th percentile criteria resulted in wider CI ranges and a barely significant effect, although the OR is similar to that for the 10 th percentile (both ORs average at − 0.73).
