Forest plot of RR results. The fixed-effects pooled SMD for RR outcomes was 0.34 (95%CI 0.02, 0.65) which signifies a small to moderate treatment effect. A positive result indicates a better score on the RR test and overall improved outcome after treatment. Heterogeneity was 74%, and p-value for the model was 0.04.
