^†Data are intraclass correlation coefficients (ICCs) where 0.40<ICC≤0.60 indicate moderate agreement, 0.60<ICC≤0.80 indicate substantial agreement and ICC≥0.81 indicate almost perfect agreement. Head weight and effective head weight were omitted from the analysis because they were considered to be affected more by body weight than by the placement of landmarks by the raters. *ICC≥0.81
