CMAJ has been made aware of an error that occurred in the Feb. 27, 2017, issue.1
The statement about the incremental government cost per year if universal public coverage of an essential medicines list were added to existing public drug plans in Canada should have indicated an 11% increase in public expenditure, not an 11% reduction. The statement appears in the abstract (p. E295) and in the main Results and Interpretation sections (p. E300).
