Patients’ home address and participation in OCR (a) and ROC curves for predicting the participation in OCR (b). A Map showing the home addresses of patients. The mark of the hospital depicts the location of our hospital in Fuchu City in Tokyo. Colored dots indicate the location of home addresses of patients (red: only in-hospital cardiac rehabilitation (non-participation group), blue: participation in outpatient cardiac rehabilitation). b ROC curves of road distance, direct distance, and required time from home to hospital for predicting the participation in OCR. OCR, outpatient cardiac rehabilitation; PCI, percutaneous coronary intervention; CABG, coronary artery bypass grafting; CHF, congestive heart failure; ROC, receiver operating characteristic
