pubmed:abstractText |
In the absence of unmeasured confounding, standard methods for estimating the effects of time-varying treatments on an event are biased when a time-dependent risk factor for the event also predicts subsequent treatments and when past treatment history predicts subsequent risk factor levels. In contrast, structural models provide unbiased estimates of effects when unmeasured confounding is absent.
