All identified studies will be imported into COVIDENCE, a systematic review management software, to screen (title, abstract, and full text) and manage the results of the search. Two reviewers (CD and KO) will independently assess the titles and abstracts of the included articles based on the inclusion criteria. In the
event of discordance between the two reviewers, a third reviewer (AK) will review the titles and abstracts and will come to a final decision. From the included articles, CD and KO, will identify relevant publication by reviewing the full text. Any discordance will again be resolved by AK. A PRISMA flow diagram will be used to report final numbers of articles that are included and excluded at each stage. From the included
articles, one reviewer (CD) will work independently to extract data from the articles following a pre-specified extraction sheet. The following data will be extracted from each paper into COVIDENCE: (1) author; (2) year of publication; (3) study period; (4) study design; (5) country of acceptability study; (6) NTD being investigated; (7) pharmaceutical intervention being analyzed; (8) working definition for acceptability; (9) instrument used to measure acceptability; (10) method to analyze acceptability;
(11) threshold for acceptability; and (12) stage that they assessed acceptability of the pharmaceutical intervention (e.g., development, implementation); and (13) key findings.
