Pre-assignment details

A total of 23 patients were recruited for the study, and the initial 5 cases were excluded from the primary analysis because some of the initial RAGs were performed by invited surgeons who had lots of experience. This exclusion was prespecified in the protocol. Therefore, only the remaining 18 patients were included in the analysis.
