studiesadditional

Studiesadditional is a term used in academic publishing and data management to denote supplementary studies that are conceptually linked to a primary investigation. It functions as a label, tag, or metadata field intended to guide readers and researchers to follow-up work, replication attempts, or ancillary analyses that extend or corroborate the original findings.

Because it is not a standardized term, its exact meaning can vary by discipline, platform, or project. In some metadata schemas, studiesadditional may be used to list associated study records by identifier, while in repositories it can appear as a linked collection of related studies, datasets, or reports.

Typical uses include linking replication studies that reassess results, extension studies that explore broader populations, methodological investigations that test robustness, or data-sharing efforts that provide alternative analyses.

Origins of the term are informal; it commonly arises from collaborative teams, research information systems, or user-generated tags aiming to improve discoverability of related work. Best practice is to provide clear definitions within a project’s metadata and to avoid ambiguity with existing categories such as supplementary materials, appendices, or follow-up studies.

Limitations include inconsistent adoption, potential confusion with similar terms, and difficulties in interoperability across platforms. When used, it should be accompanied by explicit notes describing scope, criteria for inclusion, and linkage to primary publications.
