Published textual evidence in any language from 2016 onwards will be searched in Embase, MEDLINE, CINAHL, Web of Science, Scopus, and PsycINFO. Unpublished textual evidence will be searched for in specialized gray literature databases, Google, and international pain organization websites. Methodological quality will be assessed using the JBI critical appraisal checklists for textual evidence. Study selection, appraisal, data extraction, and synthesis will be conducted independently by 2 reviewers. Data synthesis will follow a meta-aggregative approach. Confidence in the findings will be graded using a modified ConQual approach. Good practice statements will be issued, where appropriate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Review
