The nasopharyngeal microbiome plays an essential role in respiratory health and disease, making it a key focus of metagenomic research. However, inconsistent reporting standards across studies hinder reproducibility, usability, and integration of these data, limiting the scientific value of nasopharyngeal metagenomic datasets. This systematic review assessed the impact of non-standardized reporting on metagenomic studies, focusing on reproducibility, usability, and integration in publicly available datasets. We screened 988 studies pertaining to research on the nasopharyngeal microbiome. Of the screened manuscripts, 227 were selected for full-text review based on detailed inclusion and exclusion criteria. Key findings included that only 78 studies (34%) had reproducible methods sections, 33 of those 78 studies (15%) provided analytically sufficient metadata, and 4% demonstrated mismatched laboratory methods incompatible with reported datasets. We attributed these inconsistencies to gaps in methodological transparency, lack of accessible metadata, and misaligned file formats, which collectively impede dataset reuse and integration. The interchangeability of nasopharyngeal aspirates (NPA) and nasopharyngeal swabs (NPS) was evaluated using reproducible datasets. Significant variation in the microbial profile between source types was confirmed, highlighting that specimen interchange would be inappropriate within a study. Our results underscore the critical need for standardized reporting guidelines in metagenomic research to improve data transparency, facilitate reproducibility, and enable broader data integration. The adoption of comprehensive and consistent reporting practices would significantly enhance the scientific utility of nasopharyngeal microbiome studies, promoting reliable, replicable, and integrative research across the field.
