and group assignment was based on characteristics that participants possess in nature (e.g., sex assigned at birth)—non-interventional, cross-sectional, and between-subjects study.
The model included fixed effects for differences between BCP areas and years. It also fitted a local linear trend of incidence rate within each area up to the start of BCP interventions to match the observable heterogeneous trends33. When analysing by intervention year, each year of BCP control...
To account for clinical and methodological heterogeneity between the included studies, a random effects model was used. Since the included studies differed as to the mix of participants, the method of awareness evaluation employed and the clinical phenomenon explored, we assumed that the true effect ...
Because the random-effect structure was the same for all models and because we were interested only in fixed effects, we used the maximum likelihood estimator (Cheng et al., 2010) to estimate the parameters; we selected the model with the lowest AIC at each step. We stopped the selection ...

However, previous simulations suggest that this approach does not always eliminate or reduce bias, and it is not clear when and why. Using Medicaid claims data from Oregon, we systematically vary the distribution of two key unobservables—fixed effects and the random error term—to examine how ...
