Invited Commentary: Code Review-An Important Step Toward Reproducible Research

Abstract

In this issue of the Journal, Vable et al. (Am J Epidemiol. 2021;190(10):2172-2177) discuss a systematic approach to code review as a way to improve reproducibility in epidemiologic research. Reproducibility needs to become a cornerstone of our work. In the present commentary, I discuss some of the implications of their proposal, other methods to reduce coding mistakes, and other methods to improve reproducibility in research in general. Finally, I discuss the fact that no one of these approaches is sufficient on its own; rather, these different steps need to become part of a culture that prioritizes reproducibility in research.
