  • a Continuous variables are described by its quartiles [i.e. median (25th percentile; 75th percentile)] and binary ones by its absolute and relative frequencies in parentheses.

  • b n.s., not significant; BMI, body mass index; EF, ejection fraction; CRP, C-reactive protein.

  • c To convert mg/dL to mmol/L for creatinine multiply by 76.26.
