Analysis in this table was made using non-imputed data.
*Significant difference between non-survivors and survivors with a p value of 0.01–<0.05 (*), 0.001–<0.01 (**) or <0.001 (***).
†Composite endpoint consisting of intensive or medium care unit admission, prolonged length of hospital stay (>7 days), loss of independent living and unplanned readmission within 30 days after discharge.
