Participants were grouped based on whether they received an sRBC transfusion. Postoperative complications were analyzed using frequentist methods, with and without propensity score matching (PSM), and a series of five Bayesian models of varying complexity that included hierarchical structures and covariates. Model comparison followed by weighted model averaging based on predictive performance was performed to integrate the results from the different models into a composite model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>After PSM (specifically matching surgical invasiveness and blood loss), sRBC transfusion was associated with increased odds of infection (OR 3.77, 95% CI 0.99\u201314.33; p = 0.046), acute kidney injury (OR 3.36, 95% CI 1.37\u20138.22; p = 0.007), liver injury (OR 3.52, 95% CI 1.64\u20137.54; p &lt; 0.001), pulmonary complications (OR 2.26, 95% CI 1.13\u20134.53; p = 0.025), and thrombocytopenia (OR 9.02, 95% CI 2.54\u201332.0; p &lt; 0.001). The composite Bayesian model yielded consistent results, with additional associations noted for cardiac events (OR 2.18, 95% highest density interval [HDI] 1.36\u20133.03) and coagulopathy (OR 3.13, 95% HDI 1.85\u20134.50). In contrast, allogeneic RBC transfusion was only associated with infection (OR 1.65, 95% HDI 1.04\u20132.59) and pulmonary complications (OR 1.73, 95% HDI 1.08\u20132.89).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>Salvaged RBC transfusion in complex spine surgery was found to be independently associated with increased risks of various complications.
