Figure Lengend Snippet: A amplitude, B duration, C volume with clinically observed amplitude and D volume with clinically observed constancy. Amplitude and volume values are presented after being Box-Cox transformed. Duration is presented untransformed. All statistical analyses were performed on Box-Cox transformed data. Dashed line indicates the threshold to identify the presence of tremor based on the ROC analysis. Statistically significant comparison groups based on clinical assessment, with Tukey HSD correction, and between people self-reporting tremor or no tremor are indicated; *p < 0.05, **p < 0.01, ***p < 0.001; ROC Receiver Operator Curve, UPDRS III Movement Disorder Society Unified Parkinson’s Disease Rating Scale, part III.

Figure Lengend Snippet: Small black dots represent the non-transformed tremor metric derived on a given day. Large black dots represent the average of the non-transformed tremor metric over 5 days. Vertical bars represent the range observed over 5 days per participant. Data is ordered based on tremor volume and stratified based on the maximum score of the rest, postural or kinetic tremor items of the MDS-UPDRS III [0–4]. The dashed line indicates the threshold for detecting the presence of tremor based on the ROC analysis. The vertical axis is square root transformed; ROC Receiver Operator Curve, MDS-UPDRS III Movement Disorder Society Unified Parkinson’s Disease Rating Scale, part III.
