Table 2 Postoperative delirium and secondary outcomes: propensity score matching and IPTW.
| Autologous transfusion (n=142) | Allogeneic transfusion (n=402) | Unadjusted estimate/OR [95% CI] | P value | IPTW-adjusted estimate/OR [95% CI] | P value | |
|---|---|---|---|---|---|---|
| POD | 6 (4.2) | 48 (11.9) | 0.33 (0.14–0.78) | 0.012 | 0.32 (0.13–0.79) | 0.014 |
| Pneumonia | 16 (11.3) | 42 (10.4) | 1.08 (0.59–2.01) | 0.786 | 1.09 (0.57–2.10) | 0.778 |
| DVT | 4 (2.8) | 16 (4.0) | 0.70 (0.23–2.13) | 0.530 | 0.86 (0.26–2.89) | 0.808 |
| LOS | 14 (9–17) | 14 (9–17) | −0.14 (−1.27–1.00) | 0.807 | −0.36 (−1.53–0.82) | 0.552 |
| OR – odds ratio; CI – confidence interval; IPTW – inverse probability of treatment weighting; POD – postoperative delirium; DVT – deep vein thrombosis; LOS – length of stay. * Estimate denotes the mean difference (for continuous outcomes) or odds ratio (for categorical outcomes), with 95% confidence intervals shown in parentheses. values were calculated from adjusted models, as specified. | ||||||
