Association between dopamine and patient attenuation. (A) Illustration of the standardised beta estimates of all independent variable coefficients included in the multiple regression model (R2adj = 0.40), predicting Direct intercept. Clinical variables of interest were disease severity, which had a negative effect on attenuation, and levodopa doses, which had a positive effect on attenuation. Error bars indicate ± 1 standard error of group mean. LDE = Levodopa dose equivalent. Significance level indicated by *P < 0.05; **P < 0.01; ns = non-significant. (B) Illustration of the relationship between Direct force overcompensation and levodopa dose equivalent, before entered into the regression model.
