Fig. 2

Bland-Altman plots of the 9 VPIT parameters. Plotted differences of (a) Tex[s]: execution time in seconds, (b) Ndp: number of dropped pegs during transport, (c) Fggo[N]: mean grasping force, (d) Fgreturn[N]: mean grasping force, (e) Nzc[1/s]go/return: number of zero-crossings of the acceleration, (f) Nzc[1/s]go/return: number of zero-crossings of the acceleration, (g) Etrajgo[cm]: trajectory error, (h) Etrajreturn[cm]: trajectory error, (i) Fcmean[N]: mean collision force. Represents subgroup 1 (n = 11); (orange square) Represents subgroup 2 (n = 20) (red broken line) Lines for 95 % CI of limits of agreement, (green broken line) Lines for 95 % CI of mean of differences
