I am doing research to predict if alcoholism is an independent risk factor for bleeding after surgery. I will perform a univariate analysis with a chi squared test to know if other factors, such as age, sex, comorbidities,... are associated with an increased risk for postoperative bleeding. Thereafter, I will perform a multivariate or multivariable logistic regression analysis to correct for the independent predictors (significant risk factors after univariate analysis) of postoperative bleeding, so I will know if alcoholism remains a significant risk factor for postoperative bleeding.
Is this a correct plan? And do I need to use multivariate or multivariable logistic regression analysis for this research?
