CMAJ has been made aware of an error that occurred in the Apr. 3, 2018, issue.1
In the first paragraph on the fourth page, the third sentence read, “Likewise, clarithromycin is a much more potent inhibitor of CYP250 3A4 than azithromycin.” This should have read, “Likewise, clarithromycin is a much more potent inhibitor of CYP450 3A4 than azithromycin.”
This has been corrected at cmaj.ca.
