  4. 3. Estimating Causal Effects Of Relapse Treatment On The Risk For Acute Myocardial Infarction Among Patients With Diffuse Large B-Cell Lymphoma

    Master-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Jakob Börsum; [2021]
    Nyckelord :Causal Inference; Survival; Analysis; Marginal Structural Model;

    Sammanfattning : This empirical register study intends to estimate average causal effects of relapse treatment on the risk for acute myocardial infarction (AMI) among patients with Diffuse B-Cell Lymphoma (DLBCL) within the potential outcome framework. The report includes a brief introduction to causal inference and survival anal- ysis and mentions specific causal parameters of interest that will be estimated. LÄS MER
