We then describe the RPSFT and IPCW methods and explain how these methods adjust for the bias, highlighting the assumptions invoked in the process. Our aim is to facilitate understanding of these complex methods using a case study to support explanations. We also discuss the implications of crossover adjustment on cost-effectiveness results.

Adjusting for Confounding in the Analysis

Apr 21, 2021  Adjusting for Confounding in the Analysis. Confounding is a type of bias, because it causes biased estimates of associations. However, confounding is different from selection bias and information bias, because it is caused by an imbalance in other risk factors, and the investigators can adjust for confounding in the analysis phase in order to minimize its effects.
