LOS, length-of-stay.
Adjusted for age, sex, and the presence of ≥1 comorbidity (binary, yes/no). sHR >1 indicates an increased probability of an event occurring during the study period in blood groups A/AB vs O/B, whereas a ratio <1 indicates a decreased probability in blood groups A/AB vs O/B.
Hazard ratio for overall survival.
