Clinical performances of the molecules for discriminating tPA treated (N = 12) vs. ineligible patients (N = 104).

*<p>The AUC of GST-π was significantly better than AUC of DJ-1 (p = 0.016). No significant difference was obtained between GST-π vs. NDKA (p = 0.11) and NDKA vs. DJ-1 (p = 0.14).</p><p>An AUC above 0.80 was estimated as significant (significance 0.05 and power 0.95, made with Power tests/Sample size item from pROC software).</p

Clinical performances of the 3 best molecules for discriminating early (blood sampling between 0 and 3 h after symptoms onset, N = 22) vs. late stroke patients (blood sampling strictly after 3 h, N = 81).

Time course of the blood concentrations of GST-π, NDKA, DJ-1, NT-proBNP and IL-6 after stroke onset.

<p>The grey dashed lines correspond to the median concentration of the molecules in the control patients. The grey lines connect the median of the box plots. 0–3 h: N = 22, 3–6 h: N = 15, 6–12 h: N = 8, 12–24 h: N = 45 and 24–36 h: N = 13. Note that there is no overlap between the different subgroup of times and that each patient has only one blood sampling within the 36 h after stroke onset.</p
