a Patients were asked 2 CES-D questions: how many days in the past week (0–7 d) (a) was everything you did an effort, and (b) could you not get going? Results are reported according to whether the patient answered that they had no versus one or more days per week where everything was an effort, or they could not get going.
Bold values indicate statistical significance.
BMI, body mass index; BNP, N-terminal pro-brain natriuretic peptide; CES-D, Center of Epidemiological Studies Depression Scale; CI, confidence interval; METS, metabolic equivalents.
