Use of Propensity Scores To Design Observational Comparative Effectiveness Studies
A partir d'une revue systématique de la littérature publiée entre 2014 et 2015, cette étude examine, dans les études sur le cancer, l'utilisation et la qualité des analyses basées sur la méthode du score de propension
In this issue of the Journal, Yao and colleagues (1) nicely document the explosive increase in use of propensity score (PS) methods in studies of cancer risk and its treatments. The reporting guidelines they develop can aid authors, reviewers, and editors to enhance the consistency of reports from such studies. However, in their focus on guidelines for PS analysis, they pay limited attention to the fundamental role of the PS in study design and the challenges to valid study design in observational settings. As a complement to their guidelines for reporting PS analysis, 1 shows some questions related to use of a PS for study design.
