Error in Abstract

In the Original Investigation titled “Prognostic Models Derived in PARADIGM-HF and Validated in ATMOSPHERE and the Swedish Heart Failure Registry to Predict Mortality and Morbidity in Chronic Heart Failure,”¹ published online January 29, 2020, there was an error in the second sentence of the Results section of the Abstract. The denominator for the number of participants should be 8399, so that the sentence reads “The mean (SD) age of participants was 64 (11.4) years, 78.2% were men (n = 6567 of 8399), and 70.6% were New York Heart Association class II (n = 8399).” This article has been corrected online.
