CMAJ has been made aware of an error that occurred in the Mar. 13, 2017, issue.1
The first sentence of the last paragraph included the formula “(weight in kg × [(150 – current hemoglobin in g/L) ÷ 100] × 2.4 + 500).” The formula should have been “(weight in kg × [(150 – current hemoglobin in g/L) ÷ 10] × 2.4 + 500).”
This has been corrected at cmaj.ca.
