Observation

The filters have been built using the following format:

- Country names in the [TW] field, truncated to search for plural, adjective & possessive forms

- Country name (truncated) in [TT] field for translated titles

- Country name (truncated) in [AD] field for author addresses

- Older/newer versions of country names were searched and included

- Regions and provincial terms were added in [TW] fields

- At least 20 city names were included in [TW] fields

- Previously or currently indexed NCBI journals were added using [Journal] or [IS].

The terms were checked for double meanings. Terms that overlapped with common author names or common acronyms were removed. If the terms were overlapping with that of another region, it was considered.

None of these filters have been validated.
