Relationship between Collider Bias and Interactions on the Log-Additive Scale
Apostolos Gkatzionis, Shaun R. Seaman, Rachael A. Hughes +1
Collider bias occurs when conditioning on a common effect (collider) of two variables . In this manuscript, we quantify the collider bias in the estimated association between…
Using Instruments for Selection to Adjust for Selection Bias in Mendelian Randomization
Apostolos Gkatzionis, Eric J. Tchetgen Tchetgen, Jon Heron +2
Selection bias is a common concern in epidemiologic studies. In the literature, selection bias is often viewed as a missing data problem. Popular approaches to adjust for bias due…
Conceptualising Natural and Quasi Experiments in Public Health
Frank de Vocht, Srinivasa Vittal Katikireddi, Cheryl McQuire +3

Framework for the Treatment And Reporting of Missing data in Observational Studies: The TARMOS framework
Katherine J Lee, Kate Tilling, Rosie P Cornish +5
Missing data are ubiquitous in medical research. Although there is increasing guidance on how to handle missing data, practice is changing slowly and misapprehensions abound, parti…
Sample-constrained partial identification with application to selection bias
Matthew Tudball, Rachael Hughes, Kate Tilling +2
Many partial identification problems can be characterized by the optimal value of a function over a set where both the function and set need to be estimated by empirical data. Desp…
