Grafos Acíclicos Dirigidos (DAGs) y reproducibilidad de estudios observacionales

Abstract

En ciencias de la salud, la reproducibilidad es menor en los estudios observacionales. En este trabajo se quiere estudiar si el uso de los gráficos dirigidos acíclicos puede mejorar la especificación de los análisis estadísticos de los estudios observacionales para facilitar su replicabilidad posterior. Los Diagramas Acíclicos Dirigidos permiten explicitar las relaciones entre las variables importantes en el modelo. Resaltan tanto el riesgo de sesgo de selección al condicionar por un efecto común, como la confusión de efectos al no condicionar por una causa común.
