“…A total of 8 out of 53 articles assessed alignment [6,19,26,30,35,44,46,47], whereas the 45 remaining articles identified alignment as an important factor when analyzing, presenting, and discussing results, but without directly assessing alignment (Additional file 5, column 2). Among the eight articles assessing alignment, five [6,19,26,30,35] had a definition of alignment (Additional file 6), while the remaining three [44,46,47] lacked a definition. Alignment data was collected by surveys [6,44,46,47], interviews [6,26,30,35], More than 100 % because some EBIs had several aims and exist in several categories observations [19,26], and reviews of documents 35].…”
