We recently reported a study on the same topic,2 based on the data of the French national survey.3 The results of both studies, using the same analysis (logistic regression), are similar and suggest to us the following comments.The Canadian study was carried out in one teaching hospital. An anesthesia follow-up program (100 007 anesthetics) and vital statistics data were used to assess operative mortality within 7 days of surgery.
