For each one of the datasets, information is provided regarding the PD and HC populations separately. It should be noted that in the case of in-the-wild datasets (EaH and SaH) no ground truth (GT) information exists in terms of number of bites. For the purpose of completion, we provide this information on calculations based on the number of detected bites (signified by the symbol next to the cell). Meal duration is calculated as the difference of the timestamps between the last and the first bite (GT bites for EaC and detected bites for the in-the-wild datasets). Finally, the notation a/s/t is used to signify average/standard deviation/total, a/s for average/standard deviation, y/n for yes/no and m/f for male/female.
