Help the NLM customer service team help you!
Please check out NLM’S new *FAQ*: https://support.nlm.nih.gov/ics/support/kbanswer.asp?deptID=28054&task=knowledge&questionID=2051 on customer service requests for in-depth research, literature searches, or literature reviews. We are happy to help with PubMed search strategy issues but don’t provide in-depth research or lit reviews.
When requesting help with your PubMed strategies, please include your search strategy in the contact request form or as a text attachment to the form since we’ll need to see how you’ve searched previously to troubleshoot what’s going on with your search.
