Propensity score adjustment using machine learning classification algorithms to control selection bias in online surveys. [PDF]

PLoS ONE, 2020
Modern survey methods may be subject to non-observable bias, from various sources. Among online surveys, for example, selection bias is prevalent, due to the sampling mechanism commonly used, whereby participants self-select from a subgroup whose ...

The impact of moderator by confounder interactions in the assessment of treatment effect modification: a simulation study

BMC Medical Research Methodology, 2022
Background When performed in an observational setting, treatment effect modification analyses should account for all confounding, where possible. Often, such studies only consider confounding between the exposure and outcome.
