Abstract
The systematic review and meta‑analysis represent the pinnacle of evidence‑based environmental science, providing a rigorous framework for synthesizing disparate research findings into coherent, quantitative conclusions. However, the process is notoriously labor‑intensive, with the data extraction phase being a critical bottleneck that can delay projects for months. The advent of sophisticated artificial intelligence (AI) and large language models (LLMs) offers a promising solution to automate this tedious task. This article explores the transformative potential of AI in systematic reviews, with a specific focus on evaluating the accuracy of two prominent tools: the established platform SciSpace and the open‑source LLM DeepSeek‑V3.2. By analyzing their performance in extracting study design and review‑specific variables from 20 environmental studies, including qualitative and quantitative data, this analysis aims to determine their viability as ``second reviewers". Accuracy was assessed against human double‑extracted data as the gold standard. Overall accuracy for quantitative data was 95.38\% (95.63\% completely correct for DeepSeek and 95.12\% for SciSpace), while overall accuracy for qualitative data was 100\%. AI‑assisted data extraction already has the capability to enhance the efficiency and scalability under professional supervision in environmental analytic research.
