Figure 4.

Graphical representation comparing percentage agreement, weighted Cohen’s kappa, and Gwet’s AC2 for each item. The items on light blue background are part of the FMMA-LE, those on light red of the FMMA-UE. Individual measurement points overlap for item Ib of the FMMA-LE and items Ia, Ib, VIa, and VIIIc of the FMMA-UE. FMMA-LE, Fugl-Meyer Motor assessment lower extremity; FMMA-UE, Fugl-Meyer Motor assessment upper extremity; gwet, Gwet’s AC1/AC2 coefficient; kappa, weighted Cohen’s kappa coefficient; pagree, percentage agreement.
