Test Characteristics of Tmax Volumes and Tmax Mismatch Ratio

Sensitivity(95% CI) Specificity (95% CI) PPV (95% CI) NPV (95% CI)
Tmax > 9.5 seconds volume ≤ 111.6 ml 0.76 (0.70–0.81) 0.82 (0.74–0.88) 0.89 (0.84–0.92) 0.64 (0.59–0.69)
Tmax > 16 seconds volume ≤ 67.0 ml 0.91 (0.87–0.94) 0.73 (0.64–0.80) 0.86 (0.83–0.89) 0.81 (0.74–0.87)
Tmax mismatch volume ≤ 58.3 ml 0.63 (0.57–0.69) 0.70 (0.61–0.77) 0.80 (0–75‐0.84) 0.50 (0.45–0.55)
Tmax mismatch ratio > 2.5 0.70 (0.64–0.76) 0.79 (0.71–0.85) 0.86 (0.82–0.90) 0.58 (0.53–0.63)

CI = confidence interval; NPV = negative predictive value; PPV = positive predictive value; Tmax = time to maximum concentration. Outcome of interest: modified Rankin Scale 0 to 2 at 90 days.
