Protocol Deviations and Reanalyses in a Derivative Study of the PREDIMED Trial

JAMA. 2018;320(21):2272. doi:10.1001/jama.2018.17893

A derivative study of the PREDIMED trial was published as a Research Letter1 in JAMA in 2014. After publication of this article, protocol deviations were discovered that were addressed in reanalyses and that require corrections to this Research Letter. A Letter of explanation2 describes the reanalyses and corrections. This article has been corrected online.
