*Estimated based on an expected cost-effectiveness threshold of £20 000 per QALY.
†Seemingly unrelated regression, adjustment for group allocation, age, gender, baseline EQ-5D-3L summary score, total costs in the year preceding the study start date, self-reported NYHA classification at baseline, the self-reported length of HF diagnosis, education level, relationship status and the presence of self-reported smoking, diabetes mellitus, psychological disorder, COPD, cancer and musculoskeletal disorder.
‡Seemingly unrelated regression with intervention group as the only predictor.
