Putting the patient in patient reported outcomes: a robust methodology for health outcomes assessment.
Through a series of Monte Carlo simulations, this paper illustrates that reliance solely on the summary score may lead to biased estimates of incremental effects, and proposes a novel two-stage approach that allows for unbiased estimation of incremental effects. The proposed methodology essentially reverses the order of the analysis, from one of 'aggregate, then estimate' to one of 'estimate, then aggregate'.

Control outcomes and exposures for improving internal validity of nonrandomized studies.
The authors review examples of control outcomes and exposures from prior studies and provide recommendations for conducting and reporting these analyses. They found that there is inconsistent terminology for these concepts, making study identification challenging. They recommend that the rigor of nonrandomized studies can be improved with inclusion of control outcomes and exposures for bias detection.
