Langham 1999.

Methods	Journals were handsearched cover‐to‐cover. There was an overlap of one year per journal to assess quality of handsearching. MEDLINE was searched (date not given) for the years 1966‐1995. The full article was obtained for records identified by MEDLINE and not found by handsearching. These were assessed by one person.
Data	14 emergency medicine journals (1966‐1995).
Comparisons	Handsearch vs MEDLINE using the Cochrane HSSS
Outcomes	A total of 710 RCTs were identified; 592 RCTs were identified by HS, 483 RCTs were identified by ES.
Notes	All 710 RCTs were full reports. An additional 285 RCT abstracts were found only by the HS but these were excluded from the analysis.
