Rapid responses are electronic letters to the editor. They enable our users to debate issues raised in articles published on thebmj.com. Although a selection of rapid responses will be included online and in print as readers' letters, their first appearance online means that they are published articles. If you need the url (web address) of an individual response, perhaps for citation purposes, simply click on the response headline and copy the url from the browser window. Letters are indexed in PubMed.
In the methods section of the MOSAICS study, we wrote: "We included
the World Bank's analytical income classification from 2009, categorising
countries into low (Bangladesh, Nepal, Vietnam), middle (China, Indonesia,
India, Malaysia, Pakistan), and high (Bahrain, Brunei, Hong Kong, Japan,
Saudi Arabia, Singapore, South Korea, Taiwan) income economies; for this
study we classified China, Hong Kong, and Taiwan as different countries
given their different economic status and healthcare systems."
Accordingly, it was stated that 16 countries participated in the study. To
avoid any political controversy, it may be more appropriate to use "16
countries/regions" instead of "16 countries".
