In the article "Preoperative Hemoglobin Levels and the Need
for Transfusion After Prosthetic Hip and Knee Surgery. Analysis
of Predictive Factors" (2002;84:216-20), by Salido et al., the statement
"This means that for each ten grams per deciliter of increase in
the preoperative hemoglobin level, the probability that the patient
will not need a transfusion increases 2.5 times" should have read,
"This means that for each ten grams per
liter
of increase in the preoperative hemoglobin level, the probability
that the patient will not need a transfusion increases 2.5 times."
