Suppementary table (online appendix) Table S1 – Inclusion criteria for stillbirths
NOTE: lower inclusion criteria may be used in individual countries, but Euro-Peristat requests
data starting at 22 weeks from all countries. Euro-Peristat also request data for stillbirths
and terminations of pregnancy separately, but some countries, as noted, could not
distinguish between spontaneous stillbirths and TOP.
