¹Mean age (standard deviation), all other values for age are median (interquartile range).

MELD-Na: Model for end-stage liver disease incorporating serum sodium; QTc: Corrected QT interval (> 440 milliseconds considered prolonged); IHD: Ischaemic heart disease; CVA/TIA: Cerebrovascular accident/transient ischaemic attack; HR: Hazard ratio; OR: Odds ratio.
