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 increase in the exposure, 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
