Box plots of OEF CNR between the lesion and its contralateral normal tissue (A), OEF average in the lesion and the normal tissue (B), and OEF SD in the normal tissue (C) in acute (6–24 hours post onset, N = 5) and subacute (1–14 days post onset, N = 25) ischemic stroke patients (Test Data 2). Red line, blue box, black whisker, and red cross indicate median, interquartile range, the range extending to 1.5 of the interquartile range, and outliers beyond the whisker range, respectively. Note that two outliers from NET in the subacute phase are not shown (34.8 and 45.1) in CNR. Asterisk (*) indicates a significant difference (p < 0.05, two-sample Kolmogorov-Smirnov test). Compared to CCTV, NET provided significantly greater CNR in the subacute phase, whereas the CNR was not significantly different in the acute phase
