Bold values indicate p Values <0.05.
Values are presented as median/IQR for non-normally distributed variables, or number (%) for categorical variables.
The percentages are calculated based on the total applicable population for each variable.
CABG, coronary artery bypass graft; Hb, haemoglobin; RBC, red blood cell; THR, total hip replacement; TKR, total knee replacement.
