In Reply.— We disagree with Dr Arida's assertion that the term time lag bias is an unnecessary departure from the well-established term publication bias. We accept that publication bias is the appropriate term when referring to studies that remain unpublished because of the direction or strength of their results. However, the term publication bias does not capture the differences between studies that remain unpublished and those that, because of the direction or strengths of their results, are published later than other studies.
