External validation of scores proposed for estimation of survival probability of patients with severe adult respiratory distress syndrome undergoing extracorporeal membrane oxygenation therapy: a retrospective study

Table 9 ROC Analysis of the PRESERVE score, RESP score and the score published by Roch and colleagues

Score		Original publication		All patients (n = 51)		v-v ECMO (n = 36)
		AUC	95% CI	AUC	95% CI	AUC	95% CI
PRESERVE		0.89	0.83-0.94	0.67	0.52-0.82	0.75	0.57-0.92
RESP		0.74	0.72-0.76	0.65	0.5-0.8	0.81	0.67-0.95
	with PRESERVE population	0.92	0.89-0.97
				All patients (n = 51)
Roch		0.802	0.71-0.89	0.55	0.38-0.71
