Risk models in cardiac surgery. Differences between mean and median of estimated mortality risk. A misconception

Risk scales are complex statistical tools that enable the preoperative risk of a patient referred for a surgery to be estimated. In cardiac surgery the calculated variable is the expected hospital mortality and its usefulness lies in comparing it to the obtained hospital mortality. To make this comp...
