Standardised β-coefficients are provided with 95% CIs.

The empty cells denote variables that were tested in the univariable regression analysis showing no significant correlation (p value <0.10) with the applicable dependent variable and accordingly are not included in the applicable multivariable linear regression models (see Methods section).

BMI, body mass index; CABG, coronary artery bypass graft; NS, not significant; SAQ7-AF, Seattle Angina Questionnaire 7 angina frequency; SAQ7-PL, Seattle Angina Questionnaire 7 physical limitation; SAQ7-QL, Seattle Angina Questionnaire 7 quality of life; UAP, unstable angina pectoris.
