22. 12-months Follow-up Multivariable Predictors: The variables significantly ( P < 0.05) associated with dependent variables in univariate analyses were included in multivariable analyses Results of the logistic regression are presented using odds ratios and their 95% confidence intervals. A two-sided P value < 0.05 was required for statistical significance • Primary Endpoint No predictors • TLR No predictors • Stent Thrombosis No predictors
