Rapid Response:

Does the DATABASE bias deserve a mention?

Dear Editor,

On 28 October 2002 Dr. P. Badrinath commented on the possible
language bias (1) in the paper of Weingarten et al. (2). All sorts of
biases are being described when conducting meta-analyses (3), but database
bias seems to be overlooked. Weingarten et al. (2) searched Medline,
HealthStar, and Cochrane databases and Badrinath (1) searched Medline
alone.

The CINAHL database appears to be more appropriate to search for
subject headings like ‘primary nursing care’.
