Because the study was observational, ICA was clinically judged without randomization and 2 groups compared in the study may not be regarded as selected from same population. If factors related to outcome determined the intervention, these would be confounding factors. To adjust for confounders, the authors developed a propensity score for coronary angiography and used it to adjust for effect in addition to age, sex, and Charlson comorbidity score. Forty-four covariates were mentioned in ...Reference1. Vogrin S, Harper R, Paratz E, MacIsaac A, Burchell J, Smith B, et al.
