Nutritional epidemiology plays a pivotal role in understanding the complex interplay between diet, health, and disease. The selection of covariates in these studies is a critical methodological decision, as it influences the precision and validity of the results. This meta-epidemiological review aims to systematically evaluate and compare the methods employed for covariate selection across a diverse range of nutritional epidemiology studies [1]. Through the synthesis of data from multiple studies, we identify common practices, assess their strengths and limitations, and provide recommendations for best practices in covariate selection. This review contributes to the refinement of methodological standards in nutritional epidemiology, ultimately enhancing the quality and reliability of research in this field.
