The version of the article, “Picking the Good Apples: Statistics Versus Good Judgment in Choosing Stent Operators for a Multicenter Clinical Trial” by Howard et al that published online ahead-of-print on September 11, 2014, contained an error in the first paragraph in the right-hand column on page 2. and the equations did not print correctly. The paragraph has been revised to:
For simplicity, assume that the patients treated by a specific operator has a chance of p of having a periprocedural stroke or death (ie, poor outcome or complication). Then we are interested in including the physicians with p≤0.03 (the good apples), and excluding the physicians with p>0.03 (the bad apples). We can estimate an individual operator’s p (we will refer to this estimate as ) is by simply dividing the number of patients with a poor outcome by the number of patients studied (, where k is the number with poor outcome, and n is the number of patients studied).
The publisher regrets the error.
