title: 'metaextractoR: Data Extraction for Meta-Analysis with Large Language Models'
version: 0.1.0
abstract: Use Large Language Models (LLMs) to assist with data extraction for meta-analysis.
  This package incorporates three modular Shiny apps to implement a human-in-the-loop
  framework. (1) a manual extraction interface for abstracts, (2) refining prompt
  engineering and model selection, and (3) validation of LLM-generated outputs. These
  apps enable researchers to iteratively collaborate with LLMs, with each abstract
  undergoing double data extraction—once manually by a human researcher and once independently
  by an LLM-assisted process—to emulate the double extraction process recommended
  by international standards. Notably, the package runs fully on local machines, with
  no need for API setup or external data transfer, maximising data privacy and accessibility.
  Robust logging features further enhance transparency and reproducibility by recording
  all prompt iterations and outputs.
