Network of possible comparisons between intervention and comparator for a velocity and b distance. CPT = conventional physical therapy, FES = functional electrical stimulation, TM = treadmill, RAGT = robotic-assisted gait training, FES + TM = functional electrical stimulation combined with treadmill. The width of the lines is proportional to the numbers of studies and the size of the nodes is proportional to the sample size. Numbers along the lines refer to numbers of studies/numbers of patients corresponding to direct comparisons
