DOI: 10.1161/CIRCOUTCOMES.118.004665), we are making corrections in light of information provided by the ISCHEMIA trialists after the article was accepted.“It was on this basis that $84 million of United States National Heart, Lung, and Blood Institute (US NHLBI) funding was awarded…” should read “Eighty-four million dollars of United States National Heart, Lung, and Blood Institute (US NHLBI) funding was awarded…”.“However, on January 17, 2018, over 99% of the way through the recruitment period, an amendment was made to the clinicaltrials.gov website…” should be extended. It should read: “However, on January 17, 2018, over 99% of the way through the recruitment period,2 an amendment was made to the clinicaltrials.gov website.3 This amendment indicated that the primary endpoint for ISCHEMIA had been altered to cardiovascular death, nonfatal MI, resuscitated cardiac arrest, or hospitalization for unstable angina or heart failure. The ISCHEMIA investigators have now detailed the steps involved in the change, which began in June 2017 after a recommendation from an NHLBI-appointed Independent Advisory Panel.”1 “… the primary end point that was pre-specified and not one that was post-specified” should read “…the primary end point of cardiovascular death or nonfatal MI.3”“The trial closed to recruitment on January 31, 2018, and is expected to report within the next few months.2” should read “The trial closed to recruitment on January 31, 2018.2”“When the trial reports, we suggest that readers focus on the primary end point pre-specified not any versions edited near trial end when the great majority of events will have already accumulated.” should read “When the trial reports, we suggest that readers focus on the primary end point of cardiovascular death and nonfatal MI that was originally pre-specified (which the ISCHEMIA trial will now report as a secondary endpoint).”“…we must reflect on whether there is any meaning to the term primary end point if these goalposts can be moved at will after a trial has begun recruiting—and especially if a very prominent trial does so shortly before reporting its result…” should read “…we must reflect on whether there is any meaning to the term primary end point when goalposts are moved after a trial has begun recruiting despite the best intentions of investigators.”Finally, the title of the article is now being revised to: “‘Faith Healing’ and ‘Subtraction Anxiety’ in Unblinded Trials of Procedures: Lessons from DEFER and FAME-2 for End Points in the ISCHEMIA Trial”.The authors and editors regret these errors.Footnoteshttp://circoutcomes.ahajournals.org
