OP1 and OP2 indicate the more experienced and less experienced operators, respectively. Mean and SD denote average and standard deviation in mm, respectively. OP1 ∪ OP2 denotes that both or either of OP1 and OP2 performed visual registration. OP1∩OP2 indicates that both OP1 and OP2 performed visual registration.
