p Values are derived from Student t tests for normally distributed continuous data, and from non-parametric tests for non-normally distributed continuous data. χ2 tests were performed on categorical data. The test value represents a t value for continuous data and a Pearson χ2 value for categorical data.
BMI, body mass index; CABG, coronary artery bypass grafting; CAD, coronary artery disease; CAG, coronary angiography; CVD, cardiovascular disease; HRQOL, health-related quality of life; PCI, percutaneous coronary intervention.
