Figure 3. — The chart illustrates the rate of endovascular thrombectomy (EVT) and IV r-tPA (intravenous recombinant tissue-type plasminogen activator) treatment during the coronavirus disease 2019 (COVID-19) outbreak and the time before that. The Wilcoxon signed-rank test did not demonstrate statistically significant difference in the rate of IV r-tPA treatment between the COVID-19 outbreak and prior time (33% vs 24% [difference 8.4, 95% CI, −6.9 to 30.4, P=0.21]). Similarly, no significant difference was seen in the rate of EVT in emergent large vessel occlusion (ELVO) patients during COVID-19 outbreak and prior time (66% vs 44% [difference 21.6, 95% CI, −5.3 to 47.8., P=0.11]). (Y axis denotes the percentage of ELVO stroke patients.)
