Study characteristics
Methods	Objective To determine the sensitivity and precision of existing search strategies for retrieving child health systematic reviews (SRs) in MEDLINE using PubMed. A GOLD standard was developed, and the standard reference set of SRs was established by searching children's health SRs in DARE and manually searching SRs in various journals.
Data	All titles and abstracts in DARE (Cochrane Library, Issue 2, 2004) were searched for SRs of child health also indexed in MEDLINE. Using a hand search of 7 MEDLINE‐indexed pediatric journals All issues of each journal were searched for the following 5 years: 1994, 1997, 2000, 2002, and 2004
Comparisons	Shojania 2001, Boynton 1998, White 2001, Montori 2005, PubMed Plus
Outcomes	Sensitivity‐maximising Precision‐maximising
