  • Propensity score weighting analysis

    Dear all,
    I have a dataset and I need to do a propensity score weighting analysis. I will appreciate if someone can help me write the code for my data. Here is the data codebook and data and my research question

    id= patient ID
    persistence = Treatment failure with data value 1= failure, 0 no failure
    fad= feeding artery diameter 1 - 4 mm (continues variable
    dva+ draining veindiameter 1-5 mm (continue variable)
    age= continue variable
    bmi= continue variable
    gender = 1 female, 0 male (categorical variable)
    coildistance= 1 and 0 (categorical variable)
    coilpackdensity = 0, 1, 2 (categorical variable)
    coilctdensity= continuous variable
    fan = 1, 2, 3 (categorical variable)
    dvn= 1, 2, 3, 4 (categorical variable)
    coildiameter = continuous variable
    coillength = continuous variable

    RESEARCH QUESTION: We want to see in this retrospective study which of these factors have a significant association with persistence (treatment failure in our dataset). The editorial reviewer has pointed out that we need to perform propensity score weighting to limit bias in this retrospective analysis.

    Appreciate your kind help experts.
