Concordance rates and difference in concordance between study groups for the four CR therapies (both prescribed and attended therapies) (secondary outcome) (n = 14,874)

We used Multiple Imputation by Chained Equations to handle missing data. Baseline period: first 3 months of study period; follow-up period: complete study period minus the baseline period. Performance trends: odds ratios associated with a 1-year study follow-up, adjusted for patients’ age, gender, indication for CR, and centres’ type and size. P value: probability of trends being similar in intervention and control group
Abbreviations: CI confidence interval, CR cardiac rehabilitation, OR odds ratio
aWe excluded centres with incomplete data for this therapy. The number of centres and patients included in the analyses was therefore as follows: education: 12 centres, 11,174 patients; lifestyle modification: 15 centres, 12,649 patients; exercise training: 16 centres, 12,915 patients; and relaxation and stress management training: 15 centres, 11,324 patients
