FIV (ml)	Sensitivity (95% CI)	Specificity (95% CI)	PPV (95% CI)	NPV (95% CI)
mRS 0–2
⩽5 ml	0.4 (0.29–0.51)	0.94 (0.82–0.99)	0.92 (0.78–0.98)	0.47 (0.36–0.57)

⩽40 ml	0.89 (0.8–0.95)	0.43 (0.28–0.58)	0.73 (0.64–0.82)	0.69 (0.49–0.85)
mRS 0–1
⩽5 ml	0.43 (0.31–0.55)	0.9 (0.79–0.96)	0.83 (0.67–0.94)	0.57 (0.47–0.68)

PPV: Positive predictive value; NPV: Negative predictive value; FIV (ml): follow up infarct volume; CI: Confidence Interval.
