FR, futile recanalization; MR, meaningful recanalization; MCA, middle cerebral artery; MT, mechanical thrombectomy; TICI score, thrombolysis in cerebral infarction score. Data are presented as mean and standard deviation for normally distributed continuous variables. Non-normally distributed continuous variables are displayed as median and interquartile range and are identified by an asterisk (*). Bold values denote statistical significance at a p-value of < 0.05.
