We appreciate the comments from Tang et al.
The authors have mixed the time intervals in their comment. We have taken that into account in our answer. Tang et al are concerned that the time interval from stroke onset to computed tomography (CT) was longer in the general anesthesia (GA) group compared with the conscious sedation (CS) group, diluting the difference in the total time interval from stroke onset to recanalization between the groups. They state that the no difference in neurological outcome found might be attributed to this fact.
First, time interval from stroke onset to CT did not differ statistically (GA 97 minutes versus CS 72 minutes; P=0.2523). Neither was the time interval from stroke onset to recanalization statistically different between the groups (GA 254 minutes …
