Prognostic values of the mASPECTS and sGWR for 30-day survivors. (a) Receiver operating characteristic (ROC) curves for the mASPECTS (upper) and sGWR (lower). No significant differences in the areas under the ROC curve between the 2 systems are observed (p = 0.32). (b) The mASPECTS (upper) and sGWR (lower) scores against the age of patients at CA. More survivors (blue) than non-survivors (black) are plotted above the cut-off lines (mASPECTS ≥ 20 and sGWR ≥ 1.14). Fisher’s exact tests (mASPECTS; p = 0.007, sGWR; p = 0.006). Open squares denote the four patients with shockable rhythm (ventricular tachycardia and/or fibrillation).
