CMAJ has been made aware of an error that occurred in the Oct. 12, 2021, issue.1In the first paragraph, the sentence “We treated the patient with high-potency steroids (clobetasol ointment twice daily for 6 wk, then weekly).” should have read, “We treated the patient with high-potency steroids (clobetasol ointment twice daily for 6 wk, then daily).”This has been corrected at cmaj.ca.
