Fig 2. Partial dependence plot showing the interaction between metformin intake and motor impairment (UHDRS Motorscore).

Fig 2

Result of the analysis of the UHDRS Motorscore. This plot was produced using the estimates from the fitted linear regression models, so the UHDRS Motorscore values are adjusted for age, gender, BMI and ISCED. The p-value is assessing the effect of the interaction, that is, the differential effect of metformin intake in HD-patients compared to controls.
