Table 1 Criteria for inclusion and exclusion

The document is listed in the category of resolutions and decisions

Document other than the text of the political declaration itself (e.g., reports, papers, etc.)

The text of political declaration is an outcome of the UN General Assembly, the World Health Assembly, the ILO Conference or any other world conference, summit, forum or congress (i.e., gathering people from diverse regions of the world under the authority of the UN, WHO, WB, or ILO)

Draft political declaration because it is not validated by the assembly, conference, summit, forum, or congress

Continental, regional, or national declarations that can be implemented without considerable implication of the global health community

The title or text of political declaration contains at least the term “health” to ensure that it has a health financing view

The one disease-specific political declaration because, the disease-based initiatives are time-limited, i.e., may end with the end of the disease or the disease-related efforts may decline with the decreased severity or magnitude of the disease [36]. Furthermore, we estimate that such a kind of declaration lacks universality character on which health financing equity is grounded – the declaration deals with one disease coverage instead of variety of health issues.
