Errors in Programming and Coding Affecting Cohorts Included in the Study Deriving and Validating the PROMISE Minimal-Risk Tool

To the Editor On behalf of our coauthors, we write to report errors in our article, “Identification of Patients With Stable Chest Pain Deriving Minimal Value From Noninvasive Testing: The PROMISE Minimal-Risk Tool, a Secondary Analysis of a Randomized Clinical Trial,”¹ published online on February 15, 2017, and in the April 2017 issue of JAMA Cardiology. In this article, we reported on the development and validation of the Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) minimal-risk tool to identify patients with chest pain with normal coronary arteries and no clinical events during follow-up (minimal-risk cohort) compared with another cohort after receiving either coronary computed tomography angiography or functional testing in the original trial.
