We searched the Cochrane Pregnancy and Childbirth Group’s Trials
Register by contacting the Trials Search Co-ordinator (16 December
2011).
The Cochrane Pregnancy and Childbirth Group’s Trials Register
is maintained by the Trials Search Co-ordinator and contains trials
identified from:
1. quarterly searches of the Cochrane Central Register of
Controlled Trials (CENTRAL);
2. weekly searches of MEDLINE;
3. weekly searches of EMBASE;
4. handsearches of 30 journals and the proceedings of major
conferences;
5. weekly current awareness alerts for a further 44 journals
plus monthly BioMed Central email alerts.
Details of the search strategies for CENTRAL, MEDLINE and
EMBASE, the list of handsearched journals and conference proceedings,
and the list of journals reviewed via the current awareness
service can be found in the ‘Specialized Register’ section
within the editorial information about the Cochrane Pregnancy
and Childbirth Group.
