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.

Figure 2 Meta-analysis of trials of the effect of prosthetic disc versus cervical fusion on recovery in people with chronic disabling neck pain, using a random-effects model and the Mantel-Haenszel method. Test for heterogeneity: chi2=5.64, I2=11%, p=0.34.

Figure 3 Hypothetical meta-analysis of trials, using a random-effects model, with subgrouping by age categories. Dotted vertical line represents the threshold for clinical relevance. Test for heterogeneity: I2=67%, p=0.04. Journal of Physiotherapy 2014 60, 170-173DOI: (10.1016/j.jphys.2014.06.021) Copyright © 2014 Australian Physiotherapy Association Terms and Conditions
