The hazard ratio (95% confidence interval) for all-cause death according to the hemoglobin levels. Panel (A), unadjusted model. Panel (B), Adjusted variables: age, sex, body mass index, systolic blood pressure, current smoker, diabetes, chronic obstructive pulmonary disease, coronary heart disease, decreased estimated glomerular filtration rate, hyponatremia, in-hospital left ventricular ejection fraction, New York Heart Association class, and the use of renin-angiotensin system inhibitors, β-blockers, mineralocorticoid receptor antagonists and statin at discharge, and hospital levels. Panel (C), Adjusted variables in Model-NPs: all variables mentioned above and additional adjustment for log-transformed and standardized natriuretic peptides levels. HR, hazard ratio; CI, confidence interval.
