Figure 1. Forest plot showing the subgroup analysis by overall quality score for the prevalence of Doppler Signal (DS) in people with knee OA/pain. P- prevalence rates, 95% CI - lower and upper confidence limits of the 95% confidence interval around the mean prevalence rate. The diamond in the forest plot denotes the summary prevalence and its edges the respective 95% CIs. Three groups from the study by Hall were included: (1) - people with symptomatic OA, (2) - people with radiographic OA, (3) - people with knee pain.
