Supplementary Material for a Systematic Literature Review of Web Usability Evaluation Methods, Tools, Metrics, and Empirical Assessment

This repository provides study-level supplementary data associated with a Systematic Literature Review (SLR) of Web usability evaluation research covering publications from 2005 to 2026. The repository contains three supplementary tables: (S1) the study-level results of the Reporting and Evidence Availability Assessment (REAA), including Q1 - Q5 and overall scores; (S2) the mapping between usability evaluation approaches, instruments, supporting tools, and the corresponding primary studies; and (S3) the mapping between usability-related metrics and measures and their associated primary studies. These materials are provided to improve transparency and study-level traceability of the synthesized evidence while keeping the main manuscript concise. They should be interpreted together with the methodological definitions, eligibility criteria, data-extraction procedures, and analytical classifications described in the associated manuscript.
