*2.2. Search Strategy*

A search for HIV/AIDS publications was performed on the Web of Science (WoS) Core Collection. This database was prioritized because it has covered all scientific publications with full cited reference indexing since 1900 and allowed downloading information with a diversity of research disciplines that far outweigh other databases such as Scopus or MEDLINE [32].

We applied a search query containing the search terms of "HIV" OR "human-immunodeficiencyvirus" OR "AIDS" OR "Acquired-Immune-Deficiency-Syndrome". Data were extracted in a unit of 500 publications from the first publication in the dataset end up in 2017. As the process was conducted in July 2018, we excluded all papers published in 2018 as the partial coverage of publications published in 2018 would not fully reflect the publication trend of the year. The selection criteria for study subjects were English peer-review articles, including original articles and reviews (see Figure A1). Any paper with anonymous or no authors would be excluded. In the next step, we continue refined relevant research by using the research term "quality of life", articles could be removed if they did not include "quality of life" in titles and abstracts. Any disagreement during the screening process could be discussed with a senior researcher.
