SMD and 95% CI for the external KAM during walking with and without a valgus knee brace. The diamond represents the pooled effect size using a random effects model. The vertical line at 0 represents no difference. Data to the right of 0 represent a decrease in the peak external KAM. According to the I2 and Q statistic (P value), heterogeneity was moderate and significant.
