Preface to the AHRQ supplement.
AHRQ, through its Developing Evidence to Inform Decisions about Effectiveness (DEcIDE) Research Network, sponsored this supplement to present various strategies in the design, analysis, and conduct of health outcomes studies relevant to rare diseases. The purpose of this supplement is to disseminate illustrative examples of research methods that can be applied to understand health outcomes and potentially to stimulate new patient-centered outcomes studies for rare diseases.

Potential bias of instrumental variable analyses for observational comparative effectiveness research.
Results of instrumental variable analyses may be biased if the instrument and outcome are related through an unadjusted third variable, an instrument-outcome confounder. The authors review of 187 comparative effectiveness studies using this type of analysis, only 4 considered potential instrument-outcome confounders outside the study data.

Elective induction of labor symposium: nomenclature, research methodological issues, and outcomes.
This article focuses on key method issues in studies of elective induction of labor. The authors first identify methodological concerns with the existing literature and discuss each in return. They then review existing evidence about the relationship between elective induction and cesarean delivery.

Overview of classical test theory and item response theory for the quantitative assessment of items in developing patient-reported outcomes measures.
This article presents an overview of classical test theory and item response theory in the quantitative assessment of items and scales during the content-validity phase of patient-reported outcomes (PRO) measure development. The researchers concluded that depending on the particular type of measure and specific circumstances, either approach or both may be useful to help maximize the content validity of a PRO measure.
