Process used to link deliveries to infants within health plans and to link health plan data to birth certificates at 8 sites, 2001–2007

*Includes 6,018 infants not linked to health plan records. Because birth certificates include data on some outcomes identified around the time of birth, this subset is still useful for some MEPREP activities but may not be included in all studies.
