Aim To assess the quality of the literature search strategies (PRESS) used in recent systematic reviews of neurological conditions published in 2015-2016.
Level of Investigation Descriptive
Summary of Findings 60% of key quality criteria for literature search strategies (PRESS) used in recent systematic reviews of neurological conditions published in 2015-2016 were not met. Over 30% of search strategies relied on a single keyword to identify the neurological condition. The quality of the overall and condition-specific search strategies was not correlated to the impact factor of the publishing journal. The authors highlight that single-term hedges are insensitive for most neurological conditions tested, with the exceptions of migraine and MS. Insensitive search strategies will result in many false negatives during the course of a literature search and the failure to identify potentially important data.
