n.a., Not applicable.

^aMissingness is high in wave 3 because a portion of the sample only received a postal questionnaire that did not include the Hospital Anxiety and Depression Scale (HADS) instrument.

^bAs this column represents only the modelled data and person-years with missing data were not included in the models, there are no missing values here.
