Temporal agreement of observer-documented and PD Home diary ratings on the participant level. Agreement rates (A) and Cohen's κ values (B) for “Off”, “On without dyskinesia” and “On with dyskinesia” based on simultaneous half-hourly ratings of 40 participants from two consecutive days (8 am to 4 pm) and independent observer ratings serving as reference for the comparison. Boxplots are shown with a central mark at the median, bottom, and top edges of the boxes at 25th and 75th percentiles, respectively, whiskers out to the most extreme points within 1.5 times the interquartile range, and outliers scoring more than 1.5 × IQR but at most 3 × IQR outside the quartiles. PD, Parkinson's disease; IQR, interquartile range.
