Persistent postoperative anaemia is linked to a considerably higher risk of 1-year mortality.
The highest mortality rate occurred in the anaemia-anaemia group at 17.8%, contrasting with much lower rates in other groups.
Data from 2486 patients revealed a general 1-year mortality rate of 3.3%, underscoring the study's broad relevance.
Multivariable Cox regression analysis identified the non-anaemia-anaemia group as having the highest adjusted hazard ratio for mortality.
