ROC curve analysis of pc-ASPECTS and OPT.

Variables	AUC value	95% CI	Best Cutoff Value	Sensitivity	Specificity
pc-ASPECTS, median (IQR)	0.726	0.566–0.885	8	0.583	0.744
OPT, min, median (IQR)	0.734	0.582–0.885	476	0.651	0.75

AUC indicates area under the curve; mRS, modified Rankin Scale; pc-ASPECTS, the posterior circulation Acute Stroke Prognosis Early CT Score; OPT, onset to puncture time; IQR, interquartile range; 95% CI, 95% Confidence Interval.
