The performance of the model was assessed using the area under the receiver operating characteristic curve.

Multivariable analysis showed the associations of older age, larger body mass index, lower platelet\u2013neutrophile ratio, higher lymphocyte\u2013monocyte ratio, higher D-dimer, lower fibrinogen and lower estimated glomerular filtration rate with in-hospital death, incorporated to develop a simple risk model (5A laboratory risk score), with an area under the receiver operating characteristic of 0.736 (95% confidence interval 0.700\u20130.771) and 0.715 (95% CI 0.681\u20130.750) in the derivation and validation cohorts, respectively. Patients at low risk were more tolerant to hypothermic circulatory arrest than those at middle to high risk in terms of in-hospital mortality [odds ratio 1.814 (0.222\u201314.846); odds ratio 1.824
