The search will be performed using a sensitive strategy, in consultation with an experienced librarian, for each specific database. The search terms will include terms referring to study population of low back pain, and terms referring to study interventions—GB, PG and anticonvulsants (see online supplementary appendix 1). We will limit our search to English language. Non-randomised trials would be excluded during the study selection process.
