Milestone articles have highlighted the frequency and types of statistical errors in research,1–5 yet fundamental errors persist across various disciplines. With a background in biostatistics and over 200 articles reviewed for journals such as Heart and Addiction since 2021, two differing and distinct research areas, I (DJG) have identified 10 common statistical mistakes that authors frequently make. Together with two academic colleagues, we present these issues in a concise, direct and accessible way to help researchers avoid them. This article will not repeat the pitfalls documented previously; rather, it reflects independent observations on statistical and presentational issues frequently made by authors across various medical fields.
