2. Fig 1
The visual plot of the difference between the stopwatch–footfall count and GAITRite methods as a function of the mean value of each pair of readings for (A) walking speed, (B) cadence, and (C) stride length. The solid line marks the mean difference score between the stopwatch–footfall count and GAITRite measurements. The dashed line represents the upper and lower 95% limits of agreement between the 2 methods.
