Layered Bibliometric Datasets of Lifestyle-Based Type 2 Diabetes Research (2000–2025)

This repository contains three hierarchically constructed bibliometric datasets examining the scientific landscape of lifestyle-based type 2 diabetes research between 2000 and 2025. Data were retrieved from the Web of Science Core Collection (SCI-Expanded and SSCI) in December 2025 and processed using a layered search architecture designed to capture increasing levels of conceptual specificity.

The repository includes:

• Broad Lifestyle Dataset (n = 2679)

• Intervention-Focused Core Dataset (n = 2105)

• Structured Diet–Exercise Integration Dataset (n = 110)

Data cleaning procedures included exclusion of records indexed for 2026, removal of records without DOI information, and verification of unique Web of Science accession identifiers.

The repository contains cleaned bibliometric datasets and metadata files supporting transparency, reproducibility, and future bibliometric investigations.

Software used:R, bibliometrix, and VOSviewer.
