1The totals in this column equal the number of articles asking a particular type of question, minus instances of duplicate classification by type of company within category of type of question. These instances were: Strategic behavior questions were asked by articles classified as both tobacco and transportation, both mining and manufacturing, and both tobacco and alcohol; a therapeutic intervention question was asked by the article classified as both tobacco and transportation. The overall column total is not shown, as it is greater than the total number of included articles (n = 361) because several articles posed multiple types of questions.2The totals in this row equal the total number of articles for each type of company, minus instances where articles asked multiple types of questions, of which there are too many to list.

The overall row total is not shown, as it is greater than the total number of included articles (N = 361) because three articles were classified with two types of companies.
