* to evaluate the impact of a regionalised neonatal service to the locally organised service provisions in Germany.
*Note: All published information has been collected from the article referenced in the Marker Paper box below. Therefore, there may be variations with more advanced versions of the study.

- Follow Up
- Two assessments (1991-1994) were carried out at 6 and 8 years. Two follow-up assessments in adolescence and adulthood focussed on the highest risk group (Very Preterm/Very Low Birth Weight) of the original sample only and a control group of full term born adolescents/adults followed since birth. One assessment each was carried out at 13 years (1998-1999) and at 26 years (2010-2014).
