Variable | OR (95% CI) | p value |
---|---|---|
12-month mortality | ||
Agea | 1.05 (1.05–1.06) | < 0.001 |
Female | 0.86 (0.71–1.04) | 0.121 |
GCSa | 0.81 (0.79–0.83) | < 0.01 |
Chronic comorbidity | 2.14 (1.66–2.77) | < 0.001 |
Operative admission | 0.82 (0.68–0.98) | 0.032 |
Modified SAPS IIa, b | 1.08 (1.07–1.09) | < 0.001 |
Admission yeara | 0.98 (0.97–1.00) | 0.106 |
Platelet count, × 109/La | 1.00 (0.99–1.00) | 0.783 |
Platelet transfusion | 1.53 (0.99–2.38) | 0.058 |
Platelet count, × 109/L*Platelet transfusion interaction term | ||
≥ 100 * no transfusion | Base | |
< 100 * no transfusion | 2.18 (1.60–2.97) | < 0.001 |
< 100 * transfusion | 0.97 (0.55–1.70) | 0.912 |
No interaction term between platelet level ≥ 100 and platelet transfusion could be established due to the low number of patients receiving transfusion and strong correlation between no transfusion and normal platelet count
