*Each column is a single linear regression multivariable model. Coefficients are expressed as minutes of time in activity or VMU/min (one at each time), per (i) each unit of the continuous covariates, or (ii) a change with respect to reference category in categorical covariates.
6MWD, 6-min walking distance; HAD-A, Hospital Anxiety and Depression scale-Anxiety score; mMRC, modified Medical Research Council scale; SES, socio-economic status; VMU, vector magnitude units.
