On multivariate logistic regression analysis, although thrombocytopenia [odds ratio (OR) = 1.0, 95%CI: 1.0-1.0, P = 0.06], and admission lactate (OR = 1.82, 95%CI: 0.95-3.5, P = 0.07) showed a trend towards association with mortality, only shock during hospital stay (OR = 726, 95%CI: 8-65088, P = 0.004) was independently associated with mortality.
