Comparing approaches to identify live births using the Transformed Medicaid Statistical Information System.
The objective of this study was to evaluate the performance of five approaches to identifying live births using Transformed Medicaid Statistical Information System Analytic Files (TAF). The approaches each used a different combination of diagnosis and procedure, revenue, and place of service codes to identify live births. The findings showed that Approach 4 achieved the best match of birth counts relative to CDC birth record data; Approaches 1 and 3 resulted in overcounts of births and Approaches 2 and 5 resulted in undercounts. The authors concluded that including claims from both inpatient and other services files, and excluding codes unrelated to the delivery episode, improved accuracy of live birth identification in the TAF data.

Estimating subgroup effects in generalizability and transportability analyses.
The purpose of this article was to recommend methods for estimating subgroup-specific potential outcome means and average treatment effects in generalizability and transportability analyses, utilizing outcome model--based, weighting, and augmented weighting estimators. To exemplify this process, the authors applied the methods to data from the Coronary Artery Surgery Study (North America, 1975-1996) to compare the effect of surgery plus medical therapy vs. only medical therapy for chronic coronary artery disease in subgroups defined by history of myocardial infarction.

Integrating transformative considerations and quantitative results through a participant selection joint display in explanatory sequential mixed methods studies.
This article presents a method of integrating transformative sampling considerations in explanatory sequential designs through a participant selection joint display in explanatory sequential mixed methods studies. The presented approach addressed concerns regarding transparency of research decisions in these studies, while providing a method of centering the transformative paradigm in mixed methods integration procedures.
