Kaplan\u2013Meier survival curves showed that patients with low tertile of daily energy intake had a higher mortality rate than did patients with high or middle tertile of daily energy intake. In multivariate Cox regression analyses, low daily energy intake was independently associated with higher mortality after adjustment for the model including age, sex, BNP, Charlson Comorbidity Index, history of HF hospitalization, and cachexia in addition to MNA-SF. Inclusion of both MNA-SF and energy intake into the adjustment model improved the accuracy of prediction of the mortality after discharge (continuous net reclassification improvement, 0.355, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.003; integrated discrimination improvement, 0.029, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.003).
