2. Figure 1
Meta-analysis of trials of the effect of cueing versus no cueing on gait speed (cm/s) in people with Parkinson's disease, using a random-effect model.
A negative mean gait speed means a slower overall gait speed, SD=standard deviation, total=number of participants. Test for heterogeneity: chi2=4.75, I2=0%, p=0.45.
