  1. * Model A is based on a linear mixed-effect model which shows the cross sectional association of a 1-point score on the Loneliness scale with the baseline global motor score (Loneliness) as well as its association with the rate of change in motor function (Loneliness × Time) and controls for age, sex and education and their interaction with Time. Units of comparison: Time in years since baseline, Age and education in years. ** Model B includes all the same terms as Model A but also includes terms to control for two measures of social isolation ( frequency of late-life social activities and social network size and their interactions with Time).
