| Variablesa | Adjusted odds ratio* | 95% Confidence interval | P value |
|---|---|---|---|
| PLT | 2.56 | 1.98-3.31 | <0.01 |
| Gender, male | 0.40 | 0.33-0.50 | <0.01 |
| APACHE III score | 1.01 | 1.00-1.01 | <0.01 |
| RBC transfusionb | 1.50 | 1.19-1.90 | <0.01 |
| FFP transfusionb | 0.92 | 0.68-1.24 | 0.57 |

aOther confounders include centre, year and admission diagnosis. bOnly blood products transfused prior to platelets (PLT) transfusion are considered in the analysis. RBC red blood cells, FFP fresh frozen plasma, RRT renal replacement therapy, APACHE III Acute Physiology And Chronic Health Evaluation III. *Hosmer-Lemeshow p value >0.54, area under the receiver operating characteristic curve 0.83
