However, patients in the Co group who underwent revascularization had almost significantly lower mortality than their non-treated peers (HR: 0.54; 95% CI 0.29 to 1.01; p = 0.053) ( Supplementary Fig. 1 ). 3.4 Cox Proportional Hazard Multivariate Cox regression analyses were used to explore the predictors of survival and identified age (HR 1.03; 1.01–1.04), chronic kidney disease (HR 1.81; 1.24–4.11), history of myocardial infarction (HR 1.52; 1.23–1.99) and belonging to the Co group (HR 2.88; 1.74–5.41) as independent risk factors. 4.
