Abstract
Background/aims Large language models (LLMs) have substantial potential to enhance the efficiency of academic research. The accuracy and performance of LLMs in a systematic review, a core part of evidence building, has yet to be studied in detail. Methods We introduced two LLM-based approaches of systematic review: an LLM-enabled fully automated approach (LLM-FA) utilising three different GPT-4 plugins (Consensus GPT, Scholar GPT and GPT web browsing modes) and an LLM-facilitated semi-automated approach (LLM-SA) using GPT4’s Application Programming Interface (API). We benchmarked these approaches using three published systematic reviews that reported the prevalence of diabetic retinopathy across different populations (general population, pregnant women and children). Results The three published reviews consisted of 98 papers in total. Across these three reviews, in the LLM-FA approach, Consensus GPT correctly identified 32.7% (32 out of 98) of papers, while Scholar GPT and GPT4’s web browsing modes only identified 19.4% (19 out of 98) and 6.1% (6 out of 98), respectively. On the other hand, the LLM-SA approach not only successfully included 82.7% (81 out of 98) of these papers but also correctly excluded 92.2% of 4497 irrelevant papers. Conclusions Our findings suggest LLMs are not yet capable of autonomously identifying and selecting relevant papers in systematic reviews. However, they hold promise as an assistive tool to improve the efficiency of the paper selection process in systematic reviews.
