↵† n represents number of patients in 7-day PAR analyses/7-day PAR plus imputed values/HADS depression/HADS anxiety. All models include gender, LHB area, age group as covariates. Except where stated, all models also include baseline GPPAQ as a further covariate.
CHD, coronary heart disease; GPPAQ, general practice physical activity questionnaire; HADS, Hospital Anxiety and Depression Scale; MH, mental health; 7-D PAR, 7-day physical activity recall.
