Patient characteristics based on the first imputed dataset. Values are median (interquartile range) or number of patients (%). Anemia was defined according to the World Health Organization as hemoglobin levels < 12.0 g/dl in women and < 13.0 g/dl in men. Hyponatremia was defined as sodium levels < 135 mmol/l.
