Non-inferiority analysis showing the difference between JAFROC FOM at routine dose and the lower dose configurations for CT findings causing acute neurologic deficit. Limit of non-inferiority was established a priori to be −0.10, meaning that if the lower limit of the 95% confidence interval is greater than −0.10, then non-inferiority was shown. (FOM = figure of merit; JAFROC = Jackknife alternative free-response receiver operating characteristic)
